Josh Hartnett didn't seem too thrilled about his girl Scarlett Johansson hanging out at a party with Wilmer Vaderrama. (Well with Wilmer's rep you wouldn't be would you!!!)
Wilmer flew Scarlett out to be with him in The Hamptons. 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 Scarlett on her cell phone saying:
"Wilmer was out there for a party and arranged for a helicopter for Scarlett to come out. It was just to hang out, but Josh was not psyched about it.
Finally Scarlett just handed her phone to Wilmer and said, 'Talk to Josh. Tell him we're friends.'" 
Hmmmmm bet that went down well - not!
