Chris Brown might be finally opening up about his life and struggles in his upcoming documentary, but his ex-girlfriend Karrueche Tran isn't buying it.

A Hollywood Life insider has claimed that the 27-year-old model and actress slammed Brown's documentary "Welcome To My Life," calling it a "pity party," and said that she won't be watching it anytime soon.

The trailer for Brown's documentary was released earlier this week where the singer talked about the night he assaulted another ex, Rihanna, as well as the struggles he went through as he shot to fame and stardom. However, Tran believes he's just aiming to make "people feel sorry for him."

“Karrueche won’t be watching Chris’ documentary because she’s not about to sit there and listen to his lies and take part in his pity party. Please," the source close to Tran told the publication.

Last year, it was revealed that Brown cheated on Tran with Nia Guzman, whom the singer shares a daughter with, so it's no surprise that Tran has her doubts when it comes to the singer's sincerity.

"She’s so done with Chris and his crap, and him trying to make people feel sorry for him. Talk about the worse day of someone’s life. How about finding out, online none the less, that the man you’re with and love cheated on you and had a baby with someone else! Yeah, that was a pretty rough day for Karrueche. She wishes Chris well, but at the same time, she believes he’s full of games and a cheater who hasn’t learned squat,” the insider continued.

Meanwhile, Brown opened up about his assault of Rihanna on the night of the 2009 Grammy Awards and the aftermath of the horrifying case, revealing that he once considered taking his own life after he went from being "on top of the world" to being "public enemy no. 1."
