Could there be a catfight brewing between Project Runway winner Christian Siriano and The Hills girls Heidi, Whitney, and LC? At the TAO Beach Season Two Grand Opening in Las Vegas on April 12, Christian was asked what he thought of their new fashion lines.

Christian Siriano vs. The Hills: Catfight!

He told Life & Style, "It’s really sad that if I didn’t win Project Runway, I probably wouldn’t have the sponsors I have now. I would have never been able to do what they have done because they all have disposable income, and yet their work still isn’t that great! I mean, it’s fun and flirty and young, but they’re not innovators. None of them will ever be an innovative designer. Buyers and editors are looking for longevity, and hopefully they will see that in me." Who's pulling out the claws next?
