Jennifer Aniston has hit back at an ex-roommate for allegedly revealing some of her most intimate secrets. Budding author Nancy Balbirer, 40, made her thinly veiled attack in a New York City bar where she read out a story about “Jane” — who bears striking similarities to Aniston.

Balbirer said they were both aspiring actors when she allowed Jane to live rent-free in her apartment for a few months after graduating from the High School of Performing Arts.

She said Jane iced her breasts before auditions and advised her to put chicken cutlets in her bra. Jane got liposuction, a nose job and a hairline adjustment after moving to Los Angeles, and finally landed a part on a successful sitcom — about friends living together in New York.

But the pair fell out when Jane blocked Balbirer’s bid to get a part on the sitcom.

Although Aniston’s rep denied the surgery and casting claims, she admitted the Friends star had roomed with Balbirer, who she described as a “mean-spirited opportunist.”
