Actress also talks about her Golden Globe nominated work as a pill addict with chronic pain in Cake

We all know Jennifer Aniston has a banging bikini body, but don’t be surprised if you don’t see many pics of her frolicking in the ocean or in a pool.

“I basically have a real fear of going underwater,” she said last night at a special screening of Cake, her much buzzed about indie in which she stars as a woman who suffers from chronic pain and a prescription painkiller addiction after surviving a horrific accident.

Her fear made filming some scenes in the movie quite scary because her character’s treatment includes water therapy.

“I was a kid and I was riding this tricycle around a swimming pool and I drove my tricycle into the swimming pool and I didn’t let go and my brother tried to [help me],” Aniston explained. “So, I can’t go underwater and no one will believe me. I honestly can’t.”

The Friends star cracked that one pool shot in Cake took about 30 takes to get right.

Not only is Aniston up for a Golden Globe on Sunday for her work in the movie, but we wouldn’t be surprised if her name is among the best actress nominees when the Oscar nominations are announced on Jan. 15.

She went without makeup for the movie and put on some weight for the role. Fake fake scars cover her face and body.

It’s the kind of part she’d been “dying to do for years.”

Aniston said, “It’s like a catch-22. It’s you know, ‘Please let me play this part. I know I can do it.’ But then they won’t give you the part because they don’t know if you could do it.

“So, it’s hard,” she continued. “You have to just wait for that wonderful brave human being who sort of says, ‘This is interesting to me and all of us to take [the] risk and be bold.'”
