How thrilled would you be if your girlfriend was hanging out with Wilmer Valderrama?

Probably about as thrilled as Josh Hartnett, who seemed a little anxious on Monday when the noted Hollywood swordsman flew Scarlett Johansson out to be with him in the Hamptons.

“Wilmer was out there for a party and arranged for a helicopter for Scarlett to come out, too,” says a snitch. “It was just to hang out, but Josh was not psyched about it.”

Valderrama was hosting a party at the Star Room, after which the two stars left to attend a friend’s birthday celebration at the club Boutique.

Although the rendezvous was innocent, partygoers report that Josh kept calling his lady love on her cell phone.

“Finally Scarlett just handed her phone to Wilmer and said, ‘Talk to Josh. Tell him we’re friends.’”

No doubt that made him feel super better. I’d be glad that I got a chance to bang her and maybe alittle tittie fucking in there! Sometimes you gotta take what you can! If I was Josh I would have taped it or took pictures.
