We ran some pics of Christina Aguilera lovin' London last night, but what we didn't know yet was that she was getting acquainted with two of Britain's leading men: Prince Harry and Prince William! The two were spotted hanging out Paris Hilton and XTina herself last night, much to the chagrin of Christina's hubby Jordan Bratman. Oh, the drama:

"But in the midst of all the fun, lonely Wills suddenly put down his glass and said: 'Excuse me, ladies, I'm just going to say hi to Christina.' We watched him puff out his chest and stride across the packed bar to the corner where the American inger was sitting with her hubby, Jordan Bratman.

A red-faced William first had to convince her minder he was the real deal."

Cut to William swapping his digits with XTina, and later with Paris!
