Justin Timberlake introduced Madonna at the Rock and Roll Hall of Fame ceremony yesterday and used that opportunity to take a few jabs at Britney Spears. Justin started the evening off with “She has still found time to kiss someone I may or may not have publicly kissed myself while I was in the audience. Of course you know I was talking about Sean Penn.” He then joked, “The world has always been full of Madonna wannabes and I might have even dated a couple.”

Of course, that was nothing compared to the radical speech given by Madonna. She started it off by calling the audience “motherfuckers” and said the first time she met her publicist Liz Rosenberg, she was “smoking a joint”.

She also told the crowd she split a tab of ecstasy with a music executive who she gave her first demo tape to.

The 49-year-old pop star then mimicked Michael Jackson in a squeaky voice, describing how she went after and stole Jackson’s manager.

Iggy Pop, who she said was “another ass kicker from Michigan,” performed her hits “Ray of Light” and “Burning Up.”

Madonna blamed her racy speech on Justin Timberlake, who introduced her with his own ribald jokes and mocking. “He’s bringing sexy back,” she said, “I’ll get you f!”

Amazing. At 49, Madonna still manages to shock and be rebellious. Sort of like me. This one time I borrowed a book from the library and I returned it 3 weeks late. Never paid the fine either. Fuck you public library.
