Cailey Fleming is celebrating a major milestone.

On Tuesday, May 28, the IF actress, 17, took to Instagram to share a smiling photo of her on graduation day. “Bye high school 🎓,” Fleming captioned the post.

In the photo, The Walking Dead actress sported a blue graduation gown and matching cap over a black dress and sparkly black and silver heels. Her outfit was adorned with two graduation sashes as she posed in front of what appeared to be her house.

Fleming previously marked another high school milestone on Instagram, posting photos of her attending her high school prom in March.

In the carousel of photos, Fleming posed in front of the same house in a sweeping pink dress holding pink flowers to match. She was also seen showing off her Converse sneakers underneath her prom dress at home and hanging out with friends in the kitchen on the day.

Fleming spoke about her prom experience during a recent appearance on The Today Show as she promoted her new film, IF, which opened in theaters on May 17.

“My dress was freaking humongous,” she said, appearing alongside IF‘s writer and director, John Krasinski, and her costar, Ryan Reynolds. “It’s like [the film] Tangled when she has to hold all her hair,” she continued. “I was holding my dress and I was trying to dance. But it was so fun.”

During their discussion on the show, Fleming also opened up about dealing with normal life as a teenager alongside being a young actress in Hollywood. “I was going to take a break from acting to go to high school, but then IF came about,” she revealed.

“I ruined it,” Krazinski, 44, quipped, before Fleming responded. “No, no, no, no you didn’t!” she said. “It was perfect. I got to do both and I was very lucky.”

In IF, Fleming plays a girl named Bea who gains the ability to see people’s imaginary friends (or IFs).

On May 27, Fleming shared several behind-the-scenes photos from her time on set as she thanked fans for their support. Among the photos shared, Fleming was seen posing on an old armchair on set, snacking on pizza in between takes and hanging out with her costars.

“Thank you all soooooooo much for all of the love for IF!!! Seeing all of your stories and drawings and pictures is so special,” she captioned the Instagram update.
