L.A. nightspot Les Deux should have posted a “Slippery When Wet” sign on Friday night, according to Us Weekly club spies who were on the scene.

Leading the sex-crazed pack was Lauren Conrad, who got her groove on with an unidentified man (possibly Chris Richardson)… a mere three feet from her ex-boyfriend, Brody Jenner.

Lauren Conrad reportedly pranced into the club close to midnight, wearing a turquoise dress with her hair down in soft, delicate waves.

She sat at a table with other reality TV show stars Frankie Delgado (from MTV’s Twenty-four-Seven) and Shaunte & Anthony (from MTV’s Maui Fever).

The star of MTV’s The Hills was careful not to make eye contact with Brody Jenner, of course. Oh, but don’t think she didn’t know he was there!

Meanwhile, a really lame singer by the name of Jesse McCartney slithered his way over to LC’s table where he made out with some chick who totally looked like she could be his twin sister.

Then there’s seductive, underage girl-on-girl action hero Hayden Panettierre, who held a personal tongue wrestling match with VJ boyfriend Stephen Colletti (a talented young man who once two-timed LC and Kristin Cavallari – he’s a player).

Hayden and Stephen Colletti got their freak on while sitting at a table with another reality star, Dieter Schmitz (also from Laguna Beach) and Rumer Willis, who should have her own reality show at this stage.

Later, Brody Jenner apparently wasn’t fazed by LC’s flirty display, as he was seen hanging out with a gaggle of girls (including a USC blond) and recent Paris Hilton victim James Blunt.

Just another hot night on the club scene. Imagine what must have gone down at Hyde.
