Lady Gaga is speculated to have undergone plastic surgery, and her former best friend Brendan Jay Sullivan is talking about the rumors. Sullivan has written about the pop star in a tell-all titled, “Rivington Was Ours: The Lower East Side, Lady Gaga, and The Prime of Our Lives.”

He met Gaga in 2006, when he was an up-and-coming DJ in New York City, Gaga’s hometown. At the time, Gaga, whose real name is Stefani Germanotta, was a struggling artist who worked as a go-go dancer.

Since then, the 27-year-old has become a pop icon, and is now the highest-earning celebrity under the age of 30. But she has faced rumors throughout her career about her looks, and it is speculated that she has had plastic surgery -- a claim she has denied. “I have never had plastic surgery,” Lady Gaga told Harper’s Bazaar in 2011.

Yet, Sullivan is claiming that reports of Gaga having surgery may not be inaccurate, after she continuously spoke about wanting to change her appearance, specifically her nose and chest. “I’m getting a nose job,” he recalls her saying during one of their outings early in her career.

“She said it so offhand,” he went on to say. “I think she put more thought into bleaching her hair.” “It’s holding me back,” Gaga told him, Sullivan claims. “Do you think I’d be songwriting this long if I looked like the girls you date? … It’s slipping away from me.”

In addition to a nose job, the artist’s former best friend also states she wanted a breast lift. “No one will know,” the book claims she said at the time. “No one has heard of me. You won’t even be able to tell. But I will,” Gaga allegedly said.

The allegations may be shocking for Gaga’s fans, as back in September she started a Body Revolution with her fans, dubbed “little monsters,” after admitting she suffered from eating disorders bulimia and anorexia since she was 15 years old. She posted three pictures of herself wearing only a yellow bra and thong, no Photoshop and no excess weight. She showed fans that nobody is perfect and that we should all embrace our bodies, because we were born this way.
