Despite the fact that it's been rumored for years and never materialized, several sources are reporting that Britney Spears will soon record a duet with the hunky Justin Timberlake, pop/R&B star and her ex-boyfriend.

Supposedly, the long-awaited Britney-Justin collaboration will appear on Britney’s new album, which is due towards the end of this year.

Again, this is Britney Spears. You have to take these things with a grain of salt. Or a boulder of salt. But we're sure hoping it happens!

First things first - let's get this duet over, done with and climbing the charts. Then we'll work on Britney Spears and Justin Timberlake marrying and starting a huge family - both biologically and adopting, a la Brangelina.
