AFTER saying "Bye, Bye, Bye" to Britney Spears, Justin Timberlake found solace in the arms of Janet Jackson. Justin Timberlake was reportedly dating Janet Jackson - who is 15 years his senior.

The couple was spotted in action at Missy Elliot's birthday party in Miami Beach, Florida, where the two singers brazenly locked lips together in front of celebrities including Leonardo DiCaprio and Tobey Maguire.

A fellow reveler says, "Janet and Justin just started making out in front of everyone. It's like they wanted the whole place to know." And according to another source, rapper and producer Jermaine Dupri - who allegedly dated Jackson - had a close encounter with the pair together at a Los Angeles nightclub.

The spy says, "Janet had paged Jermaine and told him to come meet her at this club. But when he showed up Janet was on the dance floor grinding all over Justin. She was going buck wild. Jermaine was not happy."
