Pippa Middleton was in red again today for a visit to Wimbledon in England with her boyfriend Alex Loudon. It seems the pair are going strong despite recent rumors of a breakup. There was a round of Pippa Middleton and Prince Harry dating rumors after the royal split from his own significant other Chelsy Davy, but those stories are apparently not true at all. Pippa enjoyed a day of tennis with Alex after her sister, Kate Middleton, attended Wimbledon earlier this week with her husband, Prince William. The Middletons love the sport, since Pippa also trekked to Paris last month for the French Open. Pippa's an all-around athlete herself, having completed in both a duathlon and triathlon since her sister's wedding on April 29.
