Lisa Vanderpump: Hats Off to My New Teammates

Lisa Vanderpump showed her support for Bravo's newest housewife franchise -- "The Real Housewives of Potomac" -- when the cast stopped by PUMP Restaurant Thursday night for dinner.

Lisa wasn't there but we're told she sent a note welcoming the women to the Bravo family and hooked 'em up with PUMP hats. The new 'Housewife' franchise premieres Sunday, and we're told Bravo execs think it's going to be their new hit.

The ladies are definitely saving the drama for the cameras -- we're told there was no argument about the bill at PUMP. They each paid separately.
