Celebrities Go Glam For Lisa Vanderpump’s PUMP Lounge Launch Party (PHOTOS)

Lisa Vanderpump's party was the place to be last night.

The Real Housewives of Beverly Hills star celebrated the launch of her new bar, PUMP Lounge, in West Hollywood on May 13. Lisa looked stylish for the event, wearing a tight and low-cut purple dress with a flower on it. Who stepped out to help, ahem, pump things up? Oh, you know, just tons of Lisa's famous pals.

Real Housewives of Miami's Joanna Krupa attended the party, wearing a sexy black and white dress and rocking a super volumized hairdo. Former Real Housewives of Orange County's Gretchen Rossi and Slade Smiley also tried out the new Hollywood hotspot. Even our girl Ali Fedotowsky of Bachelorette fame walked the pink flowered carpet, wearing a bright orange collared dress and nude shoes.

As for Lisa’s RHOBH co-stars? It looks like newbies Joyce Giraud and Carlton Gebbia showed up to support the restaurateur in her new venture.
