Madonna is getting ready to release her new album, 'MDNA,' and now Britney Spears is rumored to be a featured artist on the track 'Girls Gone Wild.'

According to a leaked CD jacket, Spears is listed on the appropriately named song, while Nicki Minaj and M.I.A. each boast a track in addition to their collaborative effort on 'Give Me All Your Luvin'.' If the track listing is accurate, Minaj will be featured on the song 'Some Girls' and M.I.A. will appear on 'B-Day Song.'

Neither Madonna nor Spears has confirmed the rumor yet, however, this won't be the pop stars' first time teaming up on a song. Madge lent vocals to Spears' 2003 single 'Me Against the Music,' which appeared on the then-21-year-old's fourth album 'In the Zone.' It peaked at No. 35 on Billboard's Hot 100 chart, No. 11 on the U.S. Pop Songs chart and No. 1 on the Hot Dance Club Play chart.

‘MDNA’ will reportedly feature 18 new tracks, including three bonus songs, and is currently slated to be released on March 26. The Material girl will kick off her world tour on May 29 in Tel Aviv, Israel, and launch her North American dates on Aug. 28 in Philadelphia, Pa.
