Madonna poses in the press room at the 2009 MTV Video Music Awards in New York, September 13, 2009.
Madonna is to duet with Janet Jackson.
The two singers are working on a tribute to Janet's late brother Michael Jackson after bonding over dinner after Sunday's (13.09.09) MTV Video Music Awards (VMAs), which saw the 'Together Again' star perform 'Scream', a track originally recorded with her sibling, and Madonna make a tearful speech about her regret at "abandoning" the pop icon before his death.
A source said: "It was a meeting of two great musical minds. Madonna was so impressed with Janet's tribute to Michael that they started talking about how great it would be to honour him by doing something together.
"With that one performance Janet proved she's back on top of her game. And who better to join forces with than Madonna?
