Rockets star James Harden must be so proud.

His girlfriend, Khloe Kardashian -- the one who left him to take care of an estranged husband who got a stroke after spending a week in a Nevada brothel -- now has shared publicly that she had a one-night stand with a musician in 2008 in a video she posted on her website, khloewithak.com, via hollywoodlife.com.

Now, the Rockets star has a couple of things to worry about.

Kardashian said she attended the MTV Video Awards in 2007 (but it was determined she they actually attended the MTV Australia Video Music Awards in Sydney in 2008) with sister Kim.

"And I met a guy who was performing at the MTV awards," she proclaimed, refusing to name names, hollywoodlife.com reported. "Hooked up with him here, and like, left. He had to leave town and we both didn't live here. We all came here for the awards."

Hollywoodlife.com reeled off several artists that played at the event that, but sugarscape.com narrowed it down to Dizzee Rascal and Wyclef Jean, who was married.

"I went back to L.A. and all of a sudden, he's calling me," Khloe continued, according to sugarscape.com. "Instant messaging me on AOL, and he was like, 'I finally came out to L.A. I want to have a relationship with you.'"

The fact that she was still on AOL in 2008 is an interesting aside for someone of her means.

"He came to the States and wanted to date me again. I never saw him again because I was like, 'Uh no. You're not supposed to come here,'" she said.

Apparently, Khloe ran out of material among topics including husband Lamar Odom's health, her book tour and the fact that she actually missed more than a week of working out to keep herself in the headlines, so she dug into the archives for more material.

Now, it's Harden, in the midst of an NBA season, who's the one who has to worry about his significant other hooking up with someone else.

But even more disturbing is the fact that if Harden and Kardashian break up, she's capable of revealing secrets about him and their relationship years from now just to keep herself in the news.
