Robbie Williams has admitted to following a strict diet plan to keep his weight under control.

The Angels star has been trying to shed the weight he gained while taking time out of the limelight.

Since announcing his return to music, he is desperate to slim down to promote his new album and single, out later this year.

And he said so far it has gone well although his new diet regime consists of "not eating anything you like".

Speaking to the Sun, he said: "I've been a food ninja now for over two months. Food ninja-ry consists of not eating anything you like.

"No cake, no crisps, no chocolate. Surprisingly easier than I thought it would be. Well, easy when you've got a record coming out and you don't want to look like the Michelin man."
