Pippa Middleton Brightens Up the Billie Jean King Tennis Center

Getting an early jump on her 29th birthday festivities, Pippa Middleton attended Day Ten of the US Open in New York City last night (September 5).

The beautiful British babe looked radiant in a yellow dress as she watched the action at the USTA Billie Jean King National Tennis Center in Flushing, Queens.

During the course of the match, Pippa sat next to young tennis stud Spencer Vegosen as well as a gal pal as Scottish star Andy Murray scored another victory.

And given that Miss Middleton has shared seating with Mr. Vegosen for multiple days in a row, there are new rumors of a budding romance in the works.
