The eccentric singer - who admits he is a royalist - enjoyed watching Britain`s Prince William marry Duchess Catherine at London`s Westminster Abbey on April 29 because he felt "proud" of the British monarchy, in particular William and his brother Harry.

He said: "When those two princes stepped out onto the red carpet at that wedding it was like the whole world stopped.

"I love the fact they`re in the front line, firing a machine gun if they have to - they like a ruck, they`re like `Starsky and Hutch`! And she was a little doll. You feel proud."

Adam also revealed he once met William`s grandmother Queen Elizabeth and she recognised him even without his crazy outfits.

He told Britain`s OK! magazine: "I met the queen after the Royal Variety performance. I became friends with Liza Minnelli and she said, `Take your outfit and make-up off and wear a suit, and diamonds from Bond Street`.

"So I met the queen and she said, `Hello Adam, I didn`t recognize you without your make-up! I`m sure you don`t want to be playing to fuddy-duddies like me!`
