Macca and Stevie, Kenny and Dolly, Miss Piggy and Kermit? Forget it - the greatest pop duet of all time may be on the way with news that Britney Spears has recorded a tune with Disney star turned edgy pop powder keg Miley Cyrus

Producer Sean Garrett, who has been working with Cyrus on her new album Bangerz, suggested in a tweet yesterday that Billy Ray's daughter has recorded a song with her "dream artist" and it's believed to be none other than Britters herself.

Garret described the collaboration as "nuts" while Miley has hinted at the collaboration but has yet to identify who her female co-vocalist is.

"I have my, like, dream person on my record but I can't tell you. If I tell you then I have to kill you," she told German Kiss FM. "And I don't wanna do that because I like you, and you gotta tell me all the clubs I gotta go to so I can't tell you."

Bangerz will be Cyrus's fourth studio album and will be released here on October 7th.
