Pippa Middleton hits the Hamptons for Labor Day weekend

pippa-middleton-hamptons.jpgCelebrity sightings are a dime a dozen in the Hamptons during the summer, but Pippa Middleton nonetheless managed to cause a stir there over Labor Day weekend.

The Duchess of Cambridge's younger sister hung out with hotelier Andre Balazs on Sunday (Sept. 2) at his Sunset Beach hotel and restaurant, where she was photographed playing ping-pong with Balazs. She was in Manhattan the previous night, dining with a pair of friends, Us Weekly reports.

PICS: Pippa Middleton

Middleton blended in with the Hamptons crowd for a while, but people eventually recognized her, causing her to blush. Nonetheless, her Sunday-afternoon outing was described as "very low-key."

Canadian news anchor Melissa Grelo was at Sunset Beach Sunday as well and snapped the below photo of Middleton, casually dressed and walking barefoot with shoes in hand:
