"There's nothing diva-ish about her, she's very down to earth, very sure of herself and who she is, and I'm like a little kid, who doesn't take myself too seriously," he added at the London premiere, Thursday night.

"We had a fun script and a great director, so we just had to dive in and it was a blast."

Jen, wearing an Alexander McQueen jacket, Valentino Couture sparkling mini-dress and Jimmy Choo shoes, said of the on-screen chemistry between herself and Butler: "It's the script's fault!"

The action comedy features Gerard as a failing bounty hunter who has to bring in his bail-jumping ex-wife, played by Jen.
