Pippa was spotted in the Big Apple Wednesday in a pair of coral jeans and a light blue shirt, which she paired with Russell and Bramley Coco Pop wedges and a white straw Kate Spade Nadine purse for meetings about her just released party planning book Celebrate.
At the U.S. Open she cheered on Andy Murray in a yellow dress from Phase Eight as she sat next to Spencer Vegosen, a Harvard grad whose father is the president of the U.S. Tennis Association.
Pippa was even given a birthday cake at the U.S. Open Tennis center.
Happy birthday Pippa!
