Nick Goes Solo to Vegas

According to Yahoo News.....Are they or aren't they? You'd think if Lachey wanted to stop the tabloid attacks on his marriage, he wouldn't be going solo to Vegas. But that's what he did this past Saturday, flying in for the ubid.com auction benefiting Hurricane Katrina relief. But I'm told Lachey showed no public signs of being a single guy. The women swarmed him but he spent most of his time at the Empire ballroom event hanging with his brother, DREW, and JAMIE-LYNN SIGLER's estranged husband, AJ DISCALA. He hit the after-party at Tao with MACY GRAY, MACAULAY CULKIN, MILA KUNIS, KRISTA ALLEN, DAVID SPADE and BRITTANY MURPHY. "There were girls all over Nick, but he was behaving himself," a fellow party-goer reports. "After the auction, when we were all backstage waiting for our cars to go to Tao, AJ yelled something about going to a strip club, but Nick did not go with him." As for the buzz that Lachey was a bit smitten by JESSICA BIEL, their chit-chatting was nothing more than friendly banter. Where was Jessica Simpson that night? She was spotted hanging at the Chateau Marmont hotel in West Hollywood with LINDSAY LOHAN.
