The 30-year-old singer, who split from the reality TV star in 2009 after two years of dating and later underwent laser treatment to get a tattoo of his name removed from her butt, admits she regrets making cameos on his family's E! series, 'Keeping Up with the Kardashians.'
She told Latina magazine: ''To be stuck with that Kardashian label, that was so hurtful to me and to my career. I probably realised 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.
''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.''
Adrienne also claims she felt under pressure to stay with Rob after he cheated on her.
She said: ''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.' But women, we're supposed to be like, 'He messed up. He made a mistake.' ''
She added: ''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, and that to me was so disloyal.''
