Leaked artwork allegedly indicating Spears's feature on Madonna's new track 'Girls Gone Wild' surfaced online yesterday (February 9), but this has now been confirmed as fake.
Talking about her new album MDNA during an interview with Ryan Seacrest, Madonna revealed: "There's a lot of uptempo [songs on the album], but I also have three ballads - which I haven't done for a while!"
The star was then asked when rehearsals for her upcoming world tour would begin because fans are eager to see her live. She joked: "They want their gladiators now!"
Seacrest asked if her Super Bowl half-time performance was a hint at what supporters can expect from her new shows.
Madonna responded: "Oh God, no - I don't want to repeat myself. I never do that! I'm having auditions all next week, then I'll be shooting the video for 'Girls Gone Wild' and then I'll start rehearsals."
Questioned about the rumours of Spears appearing on the song, Madonna replied: "Is Britney on what track? No, it's just little old me. She could come on stage and perform it with me if she wants."
Madonna's new single 'Give Me All Your Luvin'' is available to download now, while her 12th studio album MDNA will be released worldwide on March 26.
