Pippa Middleton and ex Alex Loudon pair up at Wimbledon

Royal sis-in-law Pippa Middleton took in the action at Wimbledon on Wednesday (June 29), but appears to have shown up with her own doubles partner -- recent ex (or is he?) Alex Loudon.

Middleton and Loudon reportedly split in early June, but -- a source tells Us magazine -- the couple had hoped to remain friendly in a "dignified manner." And what could possibly be more dignified than taking in the tennis world's top tournament as mom and dad Middleton sit close by?

According to eye witnesses, Middleton and Loudon laughed and joked and did things that could be interpreted as either flirty or friendly.

So there you have it.
