The actress, 35, was over five months pregnant while filming the Netflix series

Justine Lupe will never forget the moment she revealed to costar Kristen Bell that she was expecting her first baby.

As a guest on The Jennifer Hudson Show alongside her Nobody Wants This castmates on Thursday, Oct. 10, the new mom recalled the exact moment she told Bell, 44, that she was pregnant. Lupe, 35, recently shared on Instagram that she was over five months pregnant while filming the hit Netflix series.

“I told Kristen first,” Lupe shared. “I still remember she had invited me over to her house to work out together, which is LOL for a pregnant woman.”

“I told her that I was pregnant,” she continues, “she was in a sheet mask, and I still remember her just freaking out and running around with this mask on her face.”

After learning the exciting news, Bell lent her costar some advice on what it’s like being a mother. “It’s the most important thing, it’s the only thing — you can go anywhere in the world, you can have anything on your bucket list, but you’re about to go on the most special endeavor,” Lupe recalls Bell telling her.

“Honestly, it was the best,” she added, admitting, “It can be a nerve-racking thing to tell people, especially in this industry as a woman.”

“So, to have a set that was filled with such support and have her [Kristen Bell] as our fearless leader and Erin [Foster, the show’s creator] as well being pregnant, I felt really comfortable and happy and excited about being pregnant on set, which is a luxury.”

Lupe has since welcomed her baby, but on Thursday, Sept. 26, she originally revealed on Instagram she was pregnant during the filming, noting that she not only hid her baby news from viewers but even tried to hide her pregnancy from the show’s cast and crew.

“Nobody Wants This is out on @netflix today! This show carried me through my first 5+ months of pregnancy with so much warmth,” Lupe revealed in her caption.

She continued to share her gratitude for “having a fully pregnant showrunner in @erinfoster, a relentless champion for motherhood in @kristenanniebell, a DP in @adrianpengcorreia who knows how to work the s— out of camera to make me look, well, not pregnant.”

Lupe then revealed the hilarious story of how her cast and crew discovered that she was expecting, writing, “And a cast and crew who supported me from the moment my Gucci skirt ripped open in both the front and backsides on set at 2am when they had no idea I was pregnant and thought I was just rapidly falling apart… I had so much fun with this show and with Morgan in particular. I hope you have fun with it too! ♥️,” she added.
