Jesse: I can't talk to Kristen!

Jesse Eisenberg has joked that he's not allowed to talk to his Adventureland co-star Kristen Stewart any more.

The two made the teen romance, which is out in September, before Kristen found fame alongside Robert Pattinson in vampire blockbuster Twilight.

Talking about Kristen's new-found fame, Jesse joked: "I am not allowed to speak to Kristen 'cos of a restraining order since the Twilight movies came out."

But The Squid And The Whale star said he knew Kristen was destined for good things.

He said: "I knew right away she would be either famous or successful.

"She's just amazing, she's an incredible actress and very unique, there are very few kind of young actresses like her, she's very serious and also very funny and she's just really wonderful in the movie."
