Pippa Middleton & Alex Loudon Back On?

Maybe Pippa Middleton isn’t single after all. Here she is with rumored ex-boyfriend Alex Loudon arriving to watch Wimbledon (after doing some shopping, it looks like).

They were photographed sitting with Pippa’s parents (I don’t have the rights to those pictures, but you can see one here).

Pippa and Alex reportedly looked “quite chummy” while watching tennis. Something tells me the interest in Pippa is not going to slow down anytime soon.
