Here's an interesting twist: in today's Gossip Roundup, you'll read about Paris Hilton and Josh Henderson's hot 'n' heavy hookup sesh at a recent party. But today, there's word that Paris may be cheating on Josh already!

Who's the (ahem) lucky man? James Blunt! (If you recall, Lindsay Lohan was hooking up with James Blunt a few weeks ago. Could Hollywood get any more incestuous?)

Paris and James "danced and held hands" before making out at a Hollywood hotspot on Wednesday, a spy tells Page Six. (Side note: if you're gonna cheat on your BF, why would you do it at one of the most popular paparazzi-packed places in L.A.?)

Later, back at Paris' house, they "had a great time" on Paris' stripper pole while friends like Cameron Diaz looked on, a source tells Us: "As James' hand went inside the back of Paris' top, we knew there was more to come. They definitely hooked up!"

The only excuse we can think of? Paris, who just started watching Desperate Housewives when she and Josh got together, got confused by his character's cheating ways, so she thought she'd follow suit.

Or, you know, because she's Paris.
