THE LORD OF THE RINGS star Dominic Monaghan's California driving licence keeps getting him into trouble - because he insisted on beaming when he had his photograph taken for it.

The actor has been pulled over twice for speeding recently in Hawaii - where he's shooting hit TV series LOST - and police don't take kindly to his quirky ID.

He says, "I was pulled over twice in Hawaii and they don't appreciate it too much.

"He (police officer) said, 'What's all this about?' and I said, 'That's my smile.' He kinda said, 'Is this a joke? You think this is a joke?' and I said, 'No, it's very serious, it's gonna cost me money.'

"They don't appreciate you having fun too much. It's a bummer."
