Partying with Pippa!
Clad in a little black dress, Kate Middleton's younger sister Pippa Middleton was the guest of honor at the launch of 2&8 club at Morton's in London Thursday night.
"Pippa was with a group of female friends but knew half of the people at the event," a source told Us Weekly of the party planner. "She was the belle of the ball, everybody wanted to speak with her."
The art deco designed, members-only club served guests canapes from London's restaurants Uma, The Greenhouse and Cassis.
"Once they moved in to the main club she took seat at a table and had a glass of Moet," the source told Us of Middleton, 29. "She was on her best behavior."
Middleton did enjoy a little dancing, but not on table tops! Had she opted for table-top dancing, a rep for the club told Us their tables are "stiletto proof."
"She spent most of the evening catching up with old friends," the insider said. Middleton wrapped up the evening around 2am and stayed at the nearby Goring Hotel, where Pippa, sister Kate, 30, and the entire Middleton family stayed in advance of Kate's royal wedding to Prince William in April 2011.
