WATCH: Madonna's Son Rocco Gets Dunked On 'Ellen' ... By His Mom!

Madonna, 54, horsed around with Rocco, 12, her son with director and ex-squeeze Guy Richie, on Ellen, the NBC show hosted by Ellen DeGeneres, as part of a fundraising series to raise money for breast cancer.

"Right now, we are going to raise $10,000 by soaking whoever Madonna wants to put in that dunk tank over there," Ellen said, while wearing a replica of Madonna's signature corset with pointed breasts. Madonna, who wore a matching ensemble, got laughs by encircling her own cones with her hands while standing behind Ellen.

"Who do you want to put in there?" Ellen asked, while volunteers popped up all over the audience. The Material Girl dashed a lot of hopes, however, when she revealed, "I don't really have to think about it. My son is here and I want him in that tank," she said.

And what Madonna wants, Madonna gets, as her son Rocco came out on stage, bantered a bit with Ellen with a confidence that only a son of Madonna can muster, and then followed a scantily clad escort into the tank.

After Madonna failed to hit the target on her third try, warning that she was not a great thrower, Ellen took over and chucked a ball at the bullseye, soaking Rocco, who covered his head with his hands before finally accepting his fate.

Liam Neeson also stopped by the Ellen show earlier this month to get dunked for breast cancer, only he bared (almost) all for the event, upping the ante to $20,000.
