Speaking at the premiere of his new film 'Kung Fu Panda' in London's Leicester Square, Jack Black said he is pretty sure the 'Wanted' actress hasn't held a grudge after he let the secret slip during the film's world premiere at Cannes Film Festival.

He told BANG Showbiz: "I think she has forgiven me. I haven't spoken to her since the event. But I never spoke to her before the event either so it's pretty much the same as it always was. I think she's neutral on the subject of me."

The star made an impressive entrance as he was carried along the red carpet, before posing with a life-sized version of his character in the film, Po.

He said: "They carried me in through this back alley in Chinatown in a little ramshackle hut. Luckily they had four really strong guys. I was worried that somebody was going to get a hernia.

"And I came bursting out of it like a jack-in-a-box and did some kung fu."
