The ladies got the party started at with dinner and dancing at LAVO on Friday evening, where the group enjoyed cocktails before Vanessa hopped into the DJ booth and commandeered the mic.

The party continued as the future Mrs. Lachey was treated to a sweet serenade by a little person impersonating her fiance, who sang a 98 Degrees song while dancing for the bachelorette.

Saturday was all about fun in the sun for Vanessa and the girls as the giddy group relaxed in a poolside cabana at Marquee Dayclub at the Cosmopolitan. The bride-to-be posed for photos with fans and enjoyed sweet treats while rocking a traditional bachelorette sash and crown.
