Reese Witherspoon Grabs Jennifer Aniston's Butt at Oscars 2015: Watch Jen's Reaction!

The grabber becomes the grabbed! Jennifer Aniston found herself on the receiving end of a butt grab on Sunday, Feb. 22, when pal Reese Witherspoon passed behind her on the red carpet at the 2015 Oscars and gave her a little squeeze.

The Cake star, 46, was chatting with E! host Ryan Seacrest before the show when the sneak attack occurred. As Witherspoon walked by, she casually reached out and pinched Aniston's derriere, causing the Friends alum to yelp in surprise. 

"Oh, oh!" she reacted, turning around to see who the sassy perpetrator was. Upon coming face-to-face with the Wild star, 38 — who played her younger sister in a couple episodes of Friends back in 2000 — she cooed, "Hi, honey!" 

Seacrest explained to viewers what had happened, saying, "There was a grab. There was a grab. Here we are in a serious moment, and I saw a grab."

Aniston then raised both hands in the air as if to prove her innocence. "I didn't do it!" she said, laughing, referring to her recent streak of cheekiness on the awards show circuit.

Indeed, the Horrible Bosses 2 star has been photographed getting handsy with her fellow A-listers on multiple occasions this year. Back in January, at the 2015 Golden Globes, she grabbed a handful of Kate Hudson's booty as they passed each other on the carpet during E!'s pre show. And while hugging Emma Stone at the Oscars on Sunday, she full-on lifted the petite Birdman actress into the air.
