"[Hayden] had this grizzly bear-looking man with her [at Guy's nightclub in Hollywood]," one guest told us. "His name was Vladimir and everyone kept talking about how he was a wrestler. He was huge though, especially in comparison to how small she is. He looked like he could've eaten Hayden as a small snack."

So while guests such as Kim Kardashian and Paris Hilton danced to DJ Sam Ronson's mixes inside, Panettiere sucked face with Vlad on an outside patio, near a fireplace.

But a drunken man, identified by partygoers as Madonna's hairstylist Andy LeCompte,  decided to convert the fireplace into a urinal. Standing beside the kissing actress, LeCompte "just started peeing in front of everyone," our spies say.

"Hayden was so oblivious. The crowd around the fireplace scattered, but she and the hunky guy just stood there, holding each other and kissing. She was so close, Hayden must've gotten some pee on her shoes!" our witness recounts. (Source)
