Kim Kardashian bashed her brother's ex-girlfriend Adrienne Bailon on Twitter after the former "Cheetah Girl" trashed Rob Kardashian in Latina magazine. Bailon is the cover girl for the publication's September issue and during the interview she dished on her two-year romance with Rob and what she thought about the famous family.

In a 2010 episode of "Keeping Up With the Kardashians," Rob admitted that he cheated on Bailon and apparently "The Real" co-host still has some strong feelings about what went wrong.

"It's common knowledge that he cheated on me, and it always bothered me that people were like, 'Pero, why couldn't you forgive him?' Why are women always the ones who have to forgive? If you cheated on a man, he would be like, 'You're disgusting, and I want nothing to do with you,'" Bailon told Latina.

"But women, we're supposed to be like, 'He messed up. He made a mistake.' And, in my situation, it wasn't like, 'Oh my God! I made a mistake!' He strategically planned things out so that he could cheat on me," she added. "And that to me was so disloyal."

While the two were still dating, Bailon - who has since moved on with Def Jam Executive Lenny Santiago - appeared on a few episodes of the E! reality show. The  30-year-old told Latina that at the time she didn't think much of her appearances but not believes the show hurt her career.

"To be stuck with that Kardashian label, that was so hurtful to me and to my career," Bailon told magazine. "I probably realized that too late - not that it would've affected my decision in terms of who I dated, but it would've affected my decision to appear on the show."

"At the time, I didn't think anyone would even care," she added. "To this day, people will still say, 'You ruined Rob's life!' And I'll think, 'Damn, I was still playing with Barbie dolls when I met him.'"

Kim Kardashian wasn't too pleased with Bailon's comments and slammed her via a Twitter rant early this morning.

"Funny how she says being with a Kardashian hurt her career yet the only reason she has this article is bc she is talking about a Kardashian. #LETITGOOOOOOLETITGOOOOO (Frozen Voice)," Kardashian tweeted, adding, "So sad when people try to kick my brother when he is down. #FamilyForever."

Outspoken Khloe Kardashian, who often defends her brother on Twitter, retweed Kim's comments and added to a fan, "thought her and I were cool SMH."
