Kim Kardashian has not spoken to her brother Robert Kardashian, ever since he walked out of her wedding in May. But she stood up for her brother when his former girlfriend Adrienne Bailon blasted the Kardashians for ruining her career.

In a shocking new interview with Latina magazine, Bailon, who dated Rob from 2007 to 2009, called her former boyfriend disloyal and said she was stuck with the Kardashian label after appearing on the family's reality show.

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

"At the time, I didn't think anyone would even care. 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," she added.

Soon after contents of the interview went viral, Kim took to her Twitter account to slam Bailon, noting that the only reason the 30-year-old landed the Latina interview was because she was associated with a Kardashian.

Interestingly, Kim's show of support follows soon after a new report claimed that the brother and sister are still at odds with each other. Reportedly, Rob feels that Kim does not take him seriously, and his sister is in turn waiting for an apology from Rob for flaking her wedding ceremony.

"Rob says Kim has not reached out to him once since the wedding and they are still at odds with each other. He hasn't reached out to her either," a Kardashian family friend told HollywoodLife.

"Kim thinks Rob owes her a major apology and Rob thinks Kim doesn't care about him. Rob resents that Kim has never taken him or his feelings seriously," the source added.

Reportedly, Khloe is the only one who understands Rob, and Kim's indifference to Rob's troubles is a major point of argument between the sisters.
