The sister of the Duchess of Cambridge has been in attendance at the US Open this evening.
Pippa Middleton, wearing a colour-blocked, open-collared sheath dress, had an accreditation that stated she was at the Arthur Ashe Stadium in New York as a guest of men's world number one Roger Federer.
Reports have also suggested that she was accompanied by Spencer Vegosen, a tennis player who is a graduate of Harvard University.
Middleton, 28, had been watching Victoria Azarenka's three-set victory over defending champion Samantha Stosur before rain stopped play at Flushing Meadows.
