In the high-stakes symphony of The Voice Season 28, where raw talent collides with raw emotion under the glare of studio lights, few moments have resonated as deeply as Ava Nat’s Knockout Round performance. The 22-year-old powerhouse from Garden City, Michigan—a quaint suburb where dreams of stardom often feel as distant as the Hollywood sign—delivered a show-stopping rendition of Olivia Newton-John’s “Hopelessly Devoted to You” that propelled her past formidable rival Sadie Dahl and into the Playoffs. Airing on October 27, 2025, during the Knockouts’ premiere episode, the performance was a masterclass in vulnerability: Nat’s voice, a velvety blend of Broadway polish and soulful ache, wrapped around the ’70s classic like a lover’s reluctant goodbye. Coaches leaned in, the audience hushed, and when Niall Horan declared her the victor, the room erupted—not just in applause, but in a collective exhale of shared catharsis. “Ava is the most consistent one we have on the show,” Horan gushed, his Irish lilt thick with admiration. “Every time she comes out and gives a shadow-proof performance. Her ability to tell a story is insane.” Yet beneath the flawless runs and the standing ovation lies a layer the broadcast only hinted at: Nat’s song was no mere vocal showcase. It was a haunting homage to her older sister, Elena, who passed away at 21 from a sudden battle with leukemia, leaving a void that Nat has channeled into every note she’s sung since. In the hours after the episode, as #AvaNat trends spiked to over 500,000 mentions on X, Nat opened up in a tearful post-show interview, revealing the “hopelessly devoted” truth that fueled her fire. “This song was Elena’s anthem,” she whispered to NBC cameras, her eyes glistening under the house lights. “She’d belt it in the car, laughing like life was one big musical. Singing it now… it’s like holding her hand one more time.”

Garden City’s tree-lined streets and close-knit community might seem an unlikely breeding ground for a Voice contender, but for Ava Nat—born Ava Natalia Rossi to a high school music teacher mother and a auto mechanic father—music was the soundtrack to survival. Growing up in the modest ranch house on Elmwood Avenue, where autumn leaves blanket the lawns like forgotten confetti, Nat discovered her voice in the unlikeliest of places: her family’s weekly karaoke nights in the basement, a ritual born from her parents’ Italian-American roots and a shared love for belting show tunes over homemade lasagna. “Mom would crank up the oldies, and we’d all pile on—Dad butchering Sinatra, Elena owning the disco ball,” Nat recalled in a pre-season profile for People. At 10, she joined the local children’s chorus, her crystalline soprano cutting through holiday concerts like a spell. But it was theater that ignited her passion: Stints in community productions of Grease and Little Shop of Horrors at the Garden City Players honed her stage presence, teaching her to command a room with a glance and a growl. High school brought accolades—a lead in the choir’s regional win at the Michigan Music Educators’ Association—and whispers of Juilliard. Yet life, as Nat would learn, rarely follows the script.

The summer before her senior year shattered that harmony. Elena, the golden older sister—21, radiant, a budding graphic designer with a laugh that could disarm a storm—collapsed during a family picnic at Kensington Metropark. What started as flu-like symptoms spiraled into a leukemia diagnosis, aggressive and unforgiving. The Rossi home transformed overnight: Hospital vigils replaced karaoke sessions, Elena’s sketchbooks gathering dust beside IV stands at Beaumont Hospital in nearby Royal Oak. Nat, then 17, became her sister’s shadow—singing softly by the bedside during chemo rounds, playlists of Olivia Newton-John’s Grease soundtrack looping like a lifeline. “Elena was my first fan,” Nat shared in a heartfelt Billboard essay post-elimination. “She’d say, ‘Ava, your voice is magic—don’t ever let go.’ Even when she was weak, she’d hum along, eyes closed, pretending we were on set.” The battle lasted eight months, a blur of fundraisers at the local VFW hall—where neighbors raised $15,000 for treatments—and quiet nights where Nat would sneak into Elena’s room, strumming guitar until dawn. Elena’s final days were marked by a makeshift concert: Nat performing “Hopelessly Devoted to You” at her bedside, the sisters’ hands intertwined as monitors beeped a somber rhythm. She slipped away on a crisp October morning in 2021, leaving Nat with a journal entry scrawled in looping cursive: “Keep singing, little sis. Devotion never dies.”

Grief, for Nat, wasn’t a pause button—it was fuel. Dropping college plans at Oakland University to care for her parents, she dove into open mics at Ann Arbor’s The Ark, transforming sorrow into songcraft. Covers of Adele and Whitney Houston drew crowds, but it was her originals—raw, confessional ballads about loss—that caught the ear of a Detroit talent scout. A viral TikTok clip of her busking “Someone Like You” in front of Ford Field amassed 2 million views, landing her an audition tape for The Voice. “Applying felt like Elena’s push,” Nat told Entertainment Weekly backstage. “She always said, ‘Go big or go home.’ After she left, home felt empty—so I went big.” Her Blind Audition on September 15, 2025, was electric: A stripped-down take on Etta James’ “At Last” that had Horan spinning first, followed by McEntire and Bublé in a frenzy. “Girl, you’ve got that old-soul fire,” Horan beamed, securing her for Team Niall with a promise of “storytelling sessions over tea.” At 22, Nat entered as the season’s wildcard: A theater kid with pipes that spanned octaves, her petite frame belying a voice that could fill arenas.

The Battles tested that mettle. Paired with the velvet-voiced Kirbi—a 26-year-old from Seattle—for a duet of Fleetwood Mac’s “Landslide,” Nat’s harmonies wove through the folk-rock lament like threads of fate. Horan, eyes wide, called it “a masterclass in emotional layering,” advancing Nat while saving Kirbi for later drama. But the Knockouts—where artists pick their own songs and face off head-to-head, no steals or saves to soften the blow—loomed as the true crucible. Season 28’s format, stripped down for the first time since 2013, amplified the stakes: Eight per team, solo showdowns judged solely by the coach, with mega-mentors Joe Walsh (for Teams Niall and Reba) and Zac Brown (for Bublé and Snoop) offering battlefield wisdom. Nat drew Sadie Dahl, a 25-year-old soul sensation from Minneapolis, stolen from Snoop in the Battles for her smoky “Chandelier” cover. The matchup crackled: Dahl’s modern edge versus Nat’s timeless timbre. Nat chose “Hopelessly Devoted to You” on instinct—a song Elena had karaoked endlessly, its yearning lyrics (“Guess mine is not the first heartbroken”) mirroring the sisters’ unspoken pact. “I needed something that felt like her,” Nat explained to Walsh during rehearsals at Universal Studios Hollywood. The Eagles legend, strumming along on acoustic, advised dialing up the dreaminess: “Lean into the ache, let it breathe—Olivia would approve.”

October 27’s episode opened with the Battles’ final salvos—Team Reba’s Aubrey Nicole edging out Kenny Iko on Martina McBride’s “Independence Day”—before plunging into Knockouts fever. Horan’s trio kicked off strong: Dustin Dale Gaspard advancing over Kayleigh Clark on a bluesy “Hallelujah.” Then came Nat versus Dahl. The stage dimmed to a soft pink glow, spotlights tracing Nat’s simple black dress like a spotlight on a solitary dancer. As the piano intro swelled, she stepped forward, eyes closed, channeling Elena’s spirit. Her opening verse floated ethereal, vowels elongating like sighs, building to a bridge where her voice cracked—not with weakness, but with the weight of unspoken goodbyes. The climax? A falsetto soar on “hopelessly devoted” that hung in the air, raw and radiant, drawing gasps from the crowd. Dahl countered with a sultry “Too Good at Goodbyes,” her Sam Smith homage dripping modern soul—low notes rumbling like thunder, high runs slicing clean. Snoop, reclaiming his former steal, leaned toward Dahl: “That emotion, baby—it’s fire.” But Horan, after a tense huddle, chose Nat: “Sadie, you’re a force, but Ava… you didn’t just sing the song. You lived it.”

The broadcast cut to a quick confessional—Nat mentioning her mom’s karaoke fave—but the full story emerged in the post-show glow. On Access Hollywood the next morning, October 28, Nat unraveled the tribute’s threads: “Elena discovered Grease at 12, during her rebellious phase—pink legwarmers, the works. ‘Hopelessly Devoted’ was her breakup song after her first love ghosted her. We’d laugh about it, but deep down, it was her armor. When she got sick, she’d request it during treatments, saying it reminded her love outlasts pain.” Leukemia’s shadow loomed large: Elena’s diagnosis came mid-design internship at a Detroit ad firm, her sketches of fantastical worlds—flying cars, starlit cities—piling up unfinished. Nat became her muse, performing bedside concerts that blurred hospital beeps into backup tracks. “The night before she passed, I sang it full-out,” Nat shared, voice breaking. “She squeezed my hand on ‘I love you so,’ and whispered, ‘Devoted forever.’ That was her goodbye.” Post-loss, Nat tattooed a lyric fragment—”though I know I’ll never win”—on her wrist, a hidden talisman during auditions. Her Voice journey? A vow fulfilled: “Elena’s the reason I auditioned. This win? It’s ours.”

Fandom frenzy followed. X lit up with #AvaForElena, fans stitching edits of Nat’s performance over Grease clips and leukemia awareness PSAs. Donations to the Leukemia & Lymphoma Society spiked 25% in Michigan overnight, with Nat’s story inspiring a virtual watch party that raised $10,000. Dahl, gracious in defeat, posted a duet clip: “Ava’s light outshines us all—proud to share the stage.” Horan, mentoring with Walsh’s rock wisdom, reflected in a Rolling Stone snippet: “Ava’s consistency comes from somewhere deep. That song wasn’t performed; it was exorcised.” Season 28, already a ratings juggernaut—9.2 million premiere viewers—saw a 12% bump post-episode, buoyed by Nat’s narrative. The Knockouts continue: Team Bublé’s Jack Austin stealing hearts on “Stay,” Team Snoop’s Ralph Edwards rumbling through “Ain’t No Sunshine.” But Nat’s arc elevates the fray—her Playoffs prep, whispered to be a Whitney medley, promises more revelations.

For Nat, the road ahead is laced with legacy. Back in Garden City, her family home now hosts a makeshift shrine: Elena’s sketchbook open to a drawing of two sisters under stage lights, captioned “Our duet.” Mom Rossi, a tearful spectator at tapings, beams: “Ava’s carrying the torch—Elena’s still singing through her.” As Playoffs loom—live votes deciding fates—Nat eyes the finale, her voice a bridge across the veil. “Winning isn’t erasing the hurt,” she told fans in a heartfelt IG Live. “It’s honoring it. Elena taught me devotion’s the real superpower.” In a season of vocal fireworks, Nat’s quiet storm burns brightest: A Garden City girl, heartbroken but unbowed, proving that the sweetest harmonies rise from the deepest devotions.
