Robert Downey Jr's 12-year-old son INDIO is preparing for his own showbusiness career, after launching a rock band with his pals.

The youngster, who served as his father's best man at his wedding with producer Susan Levin this summer (05), is making the most of his musical talents and eye for style as he gets creative with his friends.

The actor says, "It used to be, 'Please, Indio, just change your clothes, brush your teeth!' Now it's the mirror and the clothes. He looks great.

"I think the band is called SAM'S WEAKNESS."
