Pippa Middleton grabbed lunch in London today with a guy friend. With no Labor Day over in the UK, it was back to work for Pippa this morning. She did, though, have a long weekend for Britain's Summer bank holiday last Monday, Aug. 29. Pippa's hanging out in London with her pals while her sister, Kate, continues to set records. Kate's wedding dress, which is on display at Buckingham Palace, became the hit of its Summer exhibition. Five-hundred thousand people are projected to check out Kate's Sarah Burton for Alexander McQueen gown before the exhibit closes on Oct. 3. Pippa's own McQueen dress from the April 29th ceremony caused a stir recently, too. Bedfordshire's Queen's Head pub had to take down a poster of Pippa's bottom after patrons said it was "disrespectful."
