abba fan madge is deep in discussions with the pair about recording together on her follow-up to no1 album confessions on a dance floor.

and even though agnetha has lived like a virtual recluse and frida hung up her high-heeled platform shoes years ago they have agreed to go into the studio.

this will be a truly massive collaboration of the music monarchy the queen of pop and the original dancing queens joining forces.

it should be a sure-fire hit if madge, seen going to the movies in londons mayfair, chooses to release their joint studio efforts as a single. a source said: madonna has been in contact with agnetha and frida for a few months.

madonna was the driving force behind the idea because she was so happy with her sample of gimme gimme gimme on hung up.

agnetha and frida loved it, they really warmed to madonna for rejuvenating one of their most famous tracks.
