Madonna's been in the studio with the artist formerly known as Avicii, who as you'll no doubt recall was officially renamed Avicci by Madonna last week.
She's popped some pictures online which seem to support this news of studio-based togetherness. That image above was posted on her Instagram account along with the following words:
"The End of a long week with Viking Leader AKA DJ Virgo AKA Avicii! So many great songs! #icantwait#revolution."
Who would have thought Madonna's #revolution would be so heavy on the rave banjos?
(There's also something going around with Madonna saying that she's working with Avicci on the re-release of his own album, rather than on her next one, so there you go.)
