When honoring Madonna at the Rock & Roll Hall of Fame ceremony on Monday, Justin couldn’t help taking a few cheap shots at his ex-girlfriend, Britney Spears.

While introducing the icon, Justin said, “The world has always been full of Madonna wannabes. I might have even dated a couple.”

The ceremony was held at the Waldorf Astoria Hotel in New York. Justin Timberlake had the honor to introduce Madonna before making her own speech.

And as Justin concluded his speech, he again made another wise crack about Britney saying, “She has still found time to kiss someone I may or may not have publicly kissed myself while I was in the audience,” Timberlake said of Madonna.

“Of course, you know, I was talking about Sean Penn.”

Madonna’s acceptance speech went a little like this:

She thanked Justin for presenting the award and than she thanked those who helped with her career, including her family and fans.  Than she called her fans “motherf**kers” and presided to tell some stories about her music career.

She openly confessed that the first time she met her long-time publicist Liz Rosenberg, she was “smoking a joint.” She also told the crowd she split a tab of ecstasy with a music exec who she gave her first demo tape to.

Madonna then mimicked Michael Jackson in a squeaky voice, describing how she went after and stole Jackson’s manager. Naturally.

Those are some speeches. But although I love Justin Timberlake, whose speech might have been a little funny, I can’t help but think that he is being a little hypocritical when it comes to bashing Britney Spears for imitating Madonna. I mean everyone knows that he wants to be the next Michael Jackson. I really don’t see a difference.
