Madonna's son Rocco made a splash on U.S. Tv after volunteering to let his superstar mum dump water on him to raise cash for charity.

The Material Girl roped the 12-year-old into joining her in an appearance on The Ellen DeGeneres show, and ordered him into a 'splash tank' for a fundraising game.

Madonna attempted to dump a bucket of water over her son by tossing baseballs at a target set up next to the tank, but she admitted her aim needed work as she repeatedly missed the mark.

She told Rocco, "This is not funny. You might never get wet, baby. I kind of suck at throwing."

DeGeneres then took over and hurled a ball at the target, netting $10,000 (£6,250) for breast cancer research and leaving the youngster dripping wet.

During the interview, which will air in the U.S. on 29 October (12), Rocco opened up about being raised by a superstar, insisting, "She's a good mother. She's very strict but in a good way."
