Pippa Cheers Andy Murray to Victory in New York

After a hard day's house hunting, Pippa Middleton celebrated her 29th birthday last night by cheering British tennis player Andy Murray to victory in the US Open quarter-final.

The Duchess of Cambridge's sister, who wore a bright yellow dress, and carried a Kate Spade straw handbag, sat next to hunky tennis ace Spencer Vegosen who she also sat with when they cheered Roger Federer to glory the previous day.
