With all that’s going on in Britney Spears’ life these days –lost her kids, lost control of heraffairs, some might even say lost her mind (although, one would have to see the medical reports to say for certain) — she probably did not need formerflame Justin Timberlake poking fun at her.

But there he was on Monday, inducting Madonna into the Rock and Roll Hall of Fame in New York and saying,”The world has long been full of Madonna wannabes, and I might have even dated couple.”

“Madonna has changed the way our world sounded, she’s changed the way our world looked and somehow she still found time to publicly kiss at least someone who I may or may not have kissed myself — while I was in the audience,” he said.

“Of course you all know who I’m talking about — Sean Penn,” jokedTimberlake.

Timberlake said he has co-written and co-produced half the tracks on Madonna’s new album “Hard Candy,” which is released next month. He spoke affectionately of Madonna injecting a shot of B12 into his bottom after he told her he was feeling unwell while they were working on the album in London.

“She looks at me and she says ‘nice top shelf’ and that was one of the greatest days of my life,” he said.

Madonna was inducted into the Rock and Roll Hall of Fame along with Leonard Cohen, rocker John Mellencamp, British pop band The Dave Clark Five and instrumental group The Ventures. You can see the video here.
