Khloe Kardashian Parties with Justin Gaston

Clothing designer Christian Audigier, of Von Dutch and Ed Hardy fame, threw a swank bash for daughter Crystal Rock’s 16th birthday Saturday night at L.A.’s Kress nightclub.

The throwdown was filmed for an episode of MTV’s My Super Sweet 16.

Celebs in attendance included Khloe Kardashian and Paris and Nicky Hilton. As well, T.I. and the Pussycat Dolls performed.

At one point Khloe sidled up to get a photo with Miley Cyrus’ boyfriend Justin Gaston, who was shirtless (again) and on call for model duties during the evening’s special runway show. What are the chances that Justin’s girlfriend will freak when she spots the shots on Khloe’s personal blog?

Alas, Miley herself wasn’t able to attend Crystal Rock’s party. She had some little thing called the American Music Awards to perform at.
