Madonna's 'Viking harem'
Madonna, Avicii and other Swedish musicians are working in the studio together.
Pop icon Madonna has shared an image on Instagram where she is sitting on the floor playing a guitar surrounded by a bunch of Swedish musicians: Vincent Pontare, Tim ”Avicii” Bergling, Salem Al Fakir, and Magnus ”Filthy” Lidehäll. Madge calls the Swedes her ”harem of Vikings”, and Avicii the ”Viking leader”.

”So many great songs,” she tweeted. ”My Viking Harem! Great Music Great Vibes! We were grinding on that. Wood!” Last month Madonna confirmed that she is working on a new album: "Yes, plans are in the works already. Don't ask me with who [I'm working with] - it's a secret. Top secret." Looks like the secret is Swedish and it’s now out in the open. Viking Leader AKA DJ Virgo AKA Avicii!
