While Lauren Conrad and Brody Jenner have had their fair share of moments when they've been a lot more than friends, they "did not sit next to each other or talk much" at Las Vegas club LAX last night and this morning.
The event? A launch party for ... the Paris Hilton Collection! Oooh!
Wearing a gray strapless dress with her hair pulled back in a ponytail, Lauren Conrad arrived around midnight, joining Brody Jenner and some pals.
"They hugged once, but it looked innocent," an onlooker said.
Lauren Conrad sipped on Grey Goose cocktails through the night.
Guest of honor Paris Hilton who turns 27 this Sunday, February 17 was considerably less low-key than The Hills star and her crew.
At one point, Hilton grabbed a microphone and sang a few of her own tunes. When her songs were over, she held on to the microphone and lip-synched to Britney Spears' recent single, "Gimme More," says a witness.
Throughout the night, Hilton, whose new flick The Hottie and the Nottie was recently voted the "worst film of all time" by IMDB was chugging water and chasing it with shots of vodka and Red Bull. Now that's hot.
Paris Hilton was also "holding hands and kissing an unidentified tall, bald man," (ruling out Stavros Niarchos) but after she left, mystery man was spotted getting cozy with another woman in a leopard-print dress.
