Vanessa Minnillo threw on a bikini to party with friends at the Marquee Day Club at The Cosmopolitan hotel in Las Vegas on Saturday. She and eight girls were there to celebrate her bachelorette, which they kicked off with a night of dancing at Lavo on Friday. The weekend was just a continuation of Vanessa's pre-wedding festivities; she and Nick Lachey had a joint shower last month, and Vanessa followed that up with an intimate bridal shower with her close pals. Vanessa's apparently happy to finish up the events since she twittered about being ready to finally tie the knot despite planning being a "breeze." The bride-to-be has yet another reason to celebrate, though, as she was recently announced as the new cohost of Wipeout.
