Is Kim Kardashian Dating Gabriel Aubry?

Kim Kardashian is making the most of her single life.

The reality star, who just celebrated her 30th birthday, has been seen stepping out with Halle Berry's ex-husband, model Gabriel Aubry, 34. Berry, who has a child with Aubry, seems to have moved on with handsome co-star Olivier Martinez, whom she recently stepped out with on the red carpet.

Kardashian, who has also been rumored to be dating Kanye West, ex-boyfriend Miles Austin and John Mayer, admitted recently that she thought she'd be married by now. She and Aubry were seen attending a Lakers game together Sunday. They are "dating a little bit," according to a source in People. But Kardashian's mom, Kris Jenner, laughed off the rumors. "They're just friends," she said on Lopez Tonight. But she added, "Isn't he hot?" –AMY LEE
