Would a Britney and Justin duet hurt Timberlake’s career?

Could it be true? Will the Mickey Mouse Club co-stars be reunited for a duet? Britney Spears is currently working on a new album and chugging along at a very slooow/almost non-existent comeback and we think-rather we KNOW-recording a smash hit with her can-do-no-wrong ex-bf Justin Timberlake could be exactly what she needs to take back her throne as the princess of pop. OK! claims that is precisely what is in the works. Please don't tease us!

Madonna recently said she would love to reunite the couple during her world tour-Britney has recorded a video that will play during Madonna's concerts while Justin appears on Madonna's single "4 Minutes." Meanwhile, Britney allegedly turned down the opportunity to work with Justin on her last album, Blackout, and we thought she was bananas.

Now the question remains: would Justin be willing to work with Brit again? Since their breakup in 2002 Timberlake recorded "Cry Me a River" and "What Goes Around Comes Around," both rumored to be about Britney's supposed adulterous ways. He's come a long way in his career and working with a washed up, pop has-been would definitely be back tracking career-wise. But wouldn't a nice, charitable favor along with potentially being responsible for reviving Britney's career be enough incentive for Justin to give it a shot?

Do you think Justin recording a duet with Britney would hurt his career or generate positive buzz and resurrect her suffering singing career? [OK]
