Paris Hilton Parties In Vegas!

What happens in Vegas, doesn’t always stay in Vegas – especially if you’re sexy socialite Paris Hilton.

The hotel heiress was snapped dirty dancing at at the Hard Rock Hotel And Casino in Las Vegas on Saturday, during a launch party for her new Web site, ParisHilton.com.

The not-so-shy Paris showed off her sexy wares as she partied hardy in a snug little black dress, dancing atop a booth, enjoying a shot, and kissing the nose of her handsome beau Doug Reinhardt.

Still, the Stars Are Blind singer said she's much more of a homebody than you'd think from these pics, thanks to the calming presence of Reinhardt.

“We’ve been together a year now and never spend a night apart," Paris told the Las Vegas Sun. "Don’t rule out a wedding in 2010... he’s taught me how to grow up and become more domestic. We don’t go out as much as I used to anymore. We stay home far more.”

Thankfully for us, Saturday was an exception.
