Britney Spears To Feature On Madonna's 'MDNA'?

Britney Spears will reportedly feature on Madonna's new album after a leaked document revealed the A-List hook up.

The Britney fansite Breathe Heavy claims that Madonna and Britney will appear together on the song 'Girls Gone Wild' with a leaked cover from the album appearing to support the claim. There has been no confirmation as to the validity of the image however.

Asked for comment, Madonna's rep neither confirmed, nor denied, that the two pop queens have collaborated for the first time since Britney's 2003 track 'Me Against The Music'.

Madonna has, however, collaborated with Nicki Minaj and MIA on the album, and performed at the Super Bowl with them this past weekend.

Meanwhile, tickets for Madonna's UK tour date - including London's Hyde Park, have gone on sale today (Feb 10). Click here for more information.
