Former child star JASON BATEMAN has warned his MR MAGORIUM'S WONDER EMPORIUM co-star ZACH MILLS to quit Hollywood - before it's too late.

The Arrested Development star, who turned to drink and drugs in his 20s after finding fame as a teenager, is only too aware of the dangers of child fame.

And he is concerned 11-year-old Mills may suffer a similar fate to him.

He says, "If I were to give him any sort of advice it would be to get the hell out of the business."
