Justin Timberlake and Britney Spears Reunite!

With so much free time suddenly on her hands, Britney Spears has been doing a lot of collaborating.

First, she filmed a video for Madonna’s Sticky & Sweet tour. Now, according to OK! Magazine, she’s singing a duet with former lover-man Justin Timberlake for her upcoming album.

While details of the collaboration are scant, if anyone can revive Spears’ flatlining music career, it’s JT.  The guy obviously keeps abreast of all the latest music trends.

Perhaps while he’s at it, Justin can even teach Britney to dress like a lady again.

But what does Timberlake get out of the deal? Besides looking like a gallant, stand-up guy willing to help an ex in need? Presumably, in exchange for the helping hand, Spears has agreed to stop spending her nights howling like a lost puppy outside Justin and Jessica Biel’s window.
