Madonna and Ellen DeGeneres are twins in a new sneak peek of "The Ellen DeGeneres Show" upcoming episode. They wear matching Gaultier Bras on top of their white button-downs that they pair with black slacks. The guest also teaches the host how to feel herself up.

During her visit, Madge raises $10,000 for breast cancer research by dunking her son Rocco. The singer gets a helping hand from the host to hit the dunk target with pink balls. "This is not funny," she says with a laugh after several failed attempts to hit the bull's eye.

Before playing the dunking game, Ellen has a brief chat with Rocco. She asks him what it's like to have a mom who is known for getting raunchy on stage. The teen also learns that the presenter is a distant relative of his family, a fact that Madge points out to him.

Each of audience members walks home with a copy of Madge's album, workout dvds and shoes from her Truth or Dare line at the end of the episode.
