Vanessa Parties Solo

Vanessa Minnillo hit the Kritik Clothing party at the Lisa Kline boutique in Beverly Hills last night sans Nick Lachey.

Although she refused to do any interviews, a source claims there was no drama—Nick simply opted to stay home last night, which is in line with denials from Nick's rep that the couple is not on the rocks. "They're good," says my source. "It was a girls' night out."

However, Vanessa arrived with just her publicist and not a group of friends. (Though, to be fair, she did chat with Stacy Keibler while scooping up free clothes.) And later she was overheard sounding heated on the phone in a backroom. "I'm sorry!" I heard her saying to someone. "Don't be pissed at me!"

Also hanging out at the same party (with considerably less scrutiny): Paula Abdul, Kim Kardashian (with new BFF Aubrey O'Day) and Haylie Duff.
