Muse's Matt Bellamy thanked girlfriend Kate Hudson as he picked up his award at the Grammy's last night (February 13) in Los Angeles.

The Muse frontman, whose band won 'Best Rock Album' for album 'The Resistance', paid tribute to the actress in his acceptance speech.

"I would like to give a special thanks to my beautiful, pregnant girlfriend over there," Bellamy told the audience.

He added: "This is a genuine surprise. It's a great honour to be here with all the great artists who have performed here tonight and everyone who has won all the awards."

The couple began dating after meeting at the Coachella festival last April and are now expecting their first baby.
