Vanessa Minnillo Celebrates Bachelorette Party in Vegas (PHOTOS)

Vanessa Minnillo, who is engaged to 98 Degrees’ Nick Lachey, hit up Sin City for a fun-filled bachelorette weekend.

Her party began at Las Vegas hot spot LAVO where she had dinner and then danced the night away. As the night went on, the bride-to-be, wearing a sash and crown, headed to the DJ booth and announced to the crowd, “I’m about to get married. I’m about to get a ball and chain, but not yet and tonight’s my bachelorette party!”

Minnillo and Lachey, the former husband of actress/singer Jessica Simpson, began dating in 2006 and announced their engagement back in November.

Last week, Nick’s brother Drew Lachey dished about the upcoming bachelor party telling Celebuzz:

“It won’t be over-the-top, but Nick is nervous about what we have in store… We are a little bit older and wiser now, so I don’t think Nick feels any need to do a crazy bachelor party again. As long as we get our core group of guys together and have fun, that’s all he wants.”

And of course, Vanessa has the family’s seal of approval. “[Nick & Vanessa] make each other very happy, and that’s all anybody could ever hope for. As his brother, I’m glad he’s finally with someone who makes him happy — and Vanessa truly does,” Drew added.
