Perhaps they're still playing doubles together after all.
Pippa Middleton and Alex Loudon, who had reportedly split
a few weeks ago, arrived at Wimbledon together on Wednesday to catch a little tennis on the tournament's second week.
Just as her older sister, the Duchess of Cambridge
, did on Monday,
Pippa turned heads at the All England Club – sporting a red dress, with her ex wearing a navy blazer and blue-and-white striped tie.
They were all smiles as they watched a quarterfinal match between Roger Federer of Switzerland and Jo-Wilfried Tsonga of France.
Pippa, 27, and Loudon, 30, a former professional cricket player turned broker, attended the Royal Wedding together in April, but Pippa's newfound celebrity was said to put a strain on the couple.
Pippa has also been spending time with George Percy, a college friend, with whom she also caught a spot of tennis
earlier this month.
