(Cover) - EN Showbiz - Madonna's new single will reportedly feature both M.I.A and Nicki Minaj.

The pop icon has apparently lined up some heavy female talent to work with her on her new record.

Sources have told website MadonnaTribe.com that nine tracks for the new album have been completed and the first single will feature both English rapper/singer M.I.A. and hip-hop star Nicki.

Few details have been released about the LP and it is as yet untitled.

However it is known that it will be produced by William Orbit, who worked with Madonna on her hit single Ray of Light and it will have a pop-dance sound.

The album will be released in spring 2012 and will follow her 2008 record Hard Candy.

Australian sister DJ-duo NERVO (Liv and Mim) are also rumoured to be working on the release.

The pair toured with Britney Spears this summer and are well known for writing some of the hottest pop tracks in the business.

So far the dup have penned singles for Ke$ha, David Guetta and Nicole Scherzinger, and they are hoping to add Madonna to the list.

"It would be amazing. Madonna is iconic," Liv told MTV News. "It would be an absolute career high! That one, you know, it's another one we'll see if the stars align. But she's expressed interest in a song of ours and she's working with William Orbit, who's an incredible producer, and who she's worked with in the past."

NERVO have a lot to thank William for. The girls revealed that he pushed their song for them and presented it to the lady herself.

"He actually was the one who pitched her the song of ours pitched it to Madonna and fingers crossed! Now that we've spoken about it, of course, it's not going to happen," Liv joked. (C) Cover Media
