After years of acting it may surprise you what Jennifer Aniston says is the scariest thing she’s ever done, and it involves taking her clothes off.

As stripper-turned-faux mother Rose in the 2013 comedy We’re the Millers, even the seasoned movie vet wasn’t immune to some stage fright on set—particularly during the striptease scene.

“I think it’s the most terrifying thing I’ve ever done in my whole entire life,” Aniston shared at the Santa Barbara International Film Festival. “People actually said, ‘What’s the scariest thing you’ve ever done?’ And I can say, honestly, it’s the striptease. It was really frightening.”

Aside from the difficulty of learning the moves, the star revealed that what really spooked her was the number of people watching her perform the scene.

“Just training with this extraordinary choreographer for two months was hard,” she say. “But nothing takes away from the fact that you’re just out there on a sound stage with 150 crew members and three cameras while you’re dancing, wearing mom jeans and mom shoes, trying to make that all work and do the choreography. It was quite some three days.”

And, the actress revealed that she is all about doing it herself: “As far as those types of scenes go, it has to be me! But of course, I was never fully ɴuᴅᴇ, never full-on,” Aniston said. “I had a body double for the end of the striptease, when I had to run out into the street and get onto the bus. There was a whole wall of paparazzis near the set, and I didn’t want them to snap those pH๏τos.”

Earlier this week, the actress shared a video with her 42.1 million Instagram followers that featured a montage of pH๏τos and videos highlighting her (many) female friendships.

Accompanied by a popular TikTok sound of Aniston’s Friends character, Rachel Green, saying, “I’ve got my girls,” the video detailed cute cameos and adorable behind-the-scenes moments from the likes of Courtney Cox, Lisa Kudrow, Kerry Washington, Jodie Turner-Smith, Drew Barrymore, and more.

At one point in the video, Aniston filmed Sandra Bullock as they laughed while making pumpkin bread. In another clip, she and Reese Witherspoon held hands in between takes of their show, The Morning Show.

Beyond just videos, the post also featured plenty of pH๏τos with her pals, including snaps of her smiling with Julia Garner, giggling with Selena Gomez, and enjoying martinis with Kate Hudson.

Naturally, plenty of Jennifer’s famous friends flooded the post’s comments to voice their love for the star, with Witherspoon writing, “Amen, sister !! So grateful to have YOU in my life ! ❤️,” and Roberts adding, “love you angel girl.”

Cox, Aniston’s longtime friend and former Friends co-star, also chimed in with a sweet message, commenting, “Thank God for you!! ❤️❤️❤️.”
