Madonna and Justin Timberlake by Kevin Mazur/ Madonna and Justin Timberlake by Kevin Mazur/

Never let it be said that Justin Timberlake isn't a man of class and distinction. In a provocative speech honoring Madonna at Monday's Rock and Roll Hall of Fame induction ceremony, he recalled exposing his sexy back(side) to Madonna, and hinted that they had once shared a celebrity lover, according to People.

His cheesy innuendo was unstoppable, citing Madonna's "shapely body of work," calling her "a woman on top... who fully enjoys that position." (Ack.)

Apparently, while collaborating on Madonna's new album, Hard Candy, she offered him a Vitamin B-12 injection, which the helpful Material Medic administered herself, after asking him to pull down his pants. "I don't know what you say to that, so I immediately dropped my pants," Timberlake said. "She gave me a shot in my a-- and looks at me and says, 'Nice top shelf.' That was one of the greatest days of my life."

He also referenced the famous (notorious?) Madonna-Britney kiss, saying that Madonna "found time to publicly kiss someone I may or may not have kissed myself - while I was in the audience. Of course, you all know who I'm talking about: Sean Penn."

Upon hearing about Timberlake's speech, Penn decked a photographer, just for old time's sake. - Mickey O'Connor
