Khloe Kardashian will face Kim Kardashian‘s ex-husband Damon Thomas when she starts her new gig on The X Factor and tension will be high considering the nasty things Damon has said about Khloe’s older sis!

Kim and Damon were married from 2000-2004 and after their divorce, the music producer who has worked with Pink and Babyface didn’t have very nice things to say about the reality star.

A source tells RadarOnline.com, “We’re sure Simon is going to have great fun with this…You know the tension is going to be unbelievable between Khloe and Damon.”

In one interview Damon said Kim is a “fame-loving, lying, plastic-surgery-loving cheat”.

“She can’t write or sing or dance, so she does harmful things in order to validate herself in the media,” he told one magazine.

Yikes!

Do you think Khloe should demand an apology from Damon when she sees him on The X Factor? What do YOU think, HollywoodLifers?

The reality star admits she has stayed with men who treated her badly and ignored the advice of her family!

Kim Kardashian may be one of the most beautiful women on the planet, but even she has fallen victim to bad boyfriends! In her new book Kardashian Konfidential the star admits to being a doormat at times and says, “I’ve always been a people pleaser. I’ve stayed with guys too long when they weren’t treating me right.”

Kim has dated a long list of famous men, among them Reggie Bush, Miles Austin, and Ray J, and was married at the age of 19 to music producer Damon Thomas.

While she admits she used to allow others to treat her however they liked, she has turned over a new leaf. “I stand up for myself more and more,” she says. “It’s so important to insist on being treated with respect.”

It seems like that’s perfect advice for every young woman!

But for the 30-year-old beauty, the one thing she wants and doesn’t have is a boyfriend. “I have always been the one in a relationship. I like that role; I want that best friend partnership,” Kim tells People magazine. While she has longed to be married like her younger sister Khloe, the reality star has learned her lesson through a series of failed relationships — including a four-year marriage to music producer Damon Thomas that ended in divorce in 2004, and a one-year relationship with NFL star Reggie Bush.

Here’s what she’s learned: Just let it happen naturally.

“I want to fall in love, but I’m not desperately looking for it,” she says. “I’m not going to try to map out who the next person I date should be.” Before, Kim was in a hurry to find her lifelong partner and start a family, but now the reality star has chilled out and said, “give me a few years before that happens. A guy isn’t the only thing that makes me happy. If I never find romance or love, that will be okay. It’s what I want, but it doesn’t define me.”

But if she does meet “the one” Kim has made it clear she will actually stop being in the spotlight as much as she has been. “ Whatever relationship I’ll be in next, I realize I can’t be this work machine all the time. It’s not realistic. I want a normal relationship.”
