It isn't easy being Rob Kardashian these days. Besides dealing with his weight issues and family discord, Adrienne Bailon has opened up about her relationship with the reality star in the September issue of Latina magazine.

While the singer talked about her regrets from her appearances on their reality show Keeping Up With the Kardashians, she also revealed he strayed during their time together.

She said to the magazine, "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.' 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."

What's interesting to note is that SheKnows went through archives of photos to see if Kardashian was photographed with any other women during that time. While nothing was found, it's entirely possible the E! personality found a way to do it on the down-low.

While the family is constantly photographed by the paparazzi, the sock entrepreneur has managed to stay out of the public eye in recent months due to his weight gain. He may have done the same thing while cheating on the former Disney star. However, no woman has blabbed to the media about her affair with him during that time. They might be afraid of the negative press.

Bailon tried her best to make the relationship work, but she realized it wasn't the right move for her in the end.

"Imagine that you realize, 'Maybe I didn't make the best decision, maybe this wasn't the best person for me, but I'm going to try to make it work.' We're so different. The way we were raised was so different," she explained. "Our thought process — we're just opposites. So I had realized that and was trying to make it work, and then you [cheat on] me? Oh no, I'm done. I'm through. I was like, 'I'm trying to make this work. I feel bad, and I want to make it work. I have your name on my a**. I want to make it work.'"

It's no secret that Kardashian was on the other end of an affair when his girlfriend after Bailon, Rita Ora, cheated on him. He was heartbroken for months over the end of their relationship and he wasn't quiet about his misery, either.

As for Bailon, she has moved on with Def Jam record executive Lenny Santiago. And yes, she is in the process of getting that "Rob" tattoo removed from her butt.
