Paris Hilton, Cameron Diaz and James Blunt Party!

Is Paris Hilton cheating on Josh Henderson?

Though Hilton has been dating the Desperate Housewives actor since late March, the heir-head was seen making out with “You’re Beautiful” crooner James Blunt, 33, at Teddy’s on Wednesday night.

A source for Page Six saw Hilton, 26, and Petra Nemcova’s ex getting cozy at the L.A. club, where they “danced and held hands” before they started making out.

Blunt’s rep huffed to Page Six, “This sounds like gossip to me!”

Uh, naw it ain’t.

Afterwards, the two left for a party at Paris’ pad, and a witness tells Usmagazine.com that Blunt and Hilton “had a great time” on Paris’ stripper pole while friends like Cameron Diaz looked on.

“As James’ hand went inside the back of Paris’ top, we knew there was more to come,” a witness at the party tells Us. “They definitely hooked up!”

And as a bonus (for you having read the whole article),

I’m happy to report that Paris Hilton’s “Nothing in this World” single has entered in the top 20 on Bulgarian Airplay Chart at #14.

You find it too late? So do I!
