Kim Kardashian Talks Justin Bieber Beef With Chelsea Handler

'I used to like her,' reality star teases about VMA host.

Everyone loves a good catfight, and it seems like one just might happen at Sunday's Video Music Awards.

VMA presenter and reality starlet Kim Kardashian admits that, since host Chelsea Handler called Justin Bieber a "two face" and blamed Kardashian for stealing her man, things have been tense.

"Chelsea and I have this, you know, [beef]," she joked at a QVC Fashion's Night Out event in New York on Friday (September 10). "I used to like her. We're on the same network, but now it's just, you know ... we can't really be in the same room together. It gets really bad on the E! studios. They have totally roped off Chelsea on one section, me on the other. You know, it's, I don't want to talk about it."

Handler has been quite open about her discomfort with Bieber's love-'em-and-leave-'em style. "He's using the flirty card with everybody he meets, and I'm not gonna fall for that," she said. "I'm 35 years old. I only have about five good years left in me, and I'm not going to waste my time on that guy."

While Kardashian might not be excited to run into Handler on Sunday night, she is looking forward to the possibility of her pal, Bieber, taking home a Moonman for Best New Artist. "That's amazing! I wish him the best of luck," she said. "I hope he wins it. I don't know who he's up against, but I hope he wins."

The 27th annual MTV Video Music Awards will be broadcast live from the Nokia Theatre in Los Angeles on Sunday. The party starts with MTV News' VMA Pre-Show at 8 p.m., followed by the main event at 9 p.m. ET/PT.
