Vanessa Minnillo will soon be a married woman – but she’s not letting her single days slip away without a proper celebration.

The gorgeous former MTV VJ jetted to Las Vegas with gal pals on Friday to celebrate her impending marriage to Nick Lachey with a good old-fashioned bachelorette bash!

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.

“I’m about to get married,” the 30-year-old beauty told the enthusiastic crowd. “I’m about to get a ball and chain…but not yet, and tonight’s my bachelorette party!”

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.
