VIDEO : Kiss and Tell? Madonna makes Michael Jackson Revelation

Madonna says she once made out with Michael Jackson after giving him a glass of chardonnay. That was among the revelations that came during the pop icon's appearance on James Corden's signature "Carpool Karaoke" segment that aired on CBS' "Late Late Show" on Wednesday. Madonna says she made the first move with Jackson because "he's a little bit shy." She says she never shared the story publicly "because no one ever asks" her.
