The veteran US singer shared a picture of herself holding up a banner across her forehead that says "The Queen" with the Arabic translation above it.

In a caption accompanying the picture, the Like A Prayer star wrote to her 11.6 million followers on Instagram: "In case someone forgot! #birthday #magic #Marakesh".

Madonna had earlier shared a "pre-birthday selfie" of herself wearing Berber clothing in what she called a celebration of the North African people's culture.

Stars from across music, film and television lined up to pass on their birthday wishes.

Australia's Kylie Minogue tweeted: "Happy birthday to Lady Madonna! I'm 14 years old, dancing and singing in my bedroom and she was just WOW!!!

"What a force and an inspiration. Enjoy your day Madonna!"

UK singer Lisa Stanfield wrote: "Happy 60th birthday your Madgesty. You've shown us and taught us more than a thing or two over the years. Long may you reign."

Little Britain star David Walliams shared a black-and-white picture of Madonna and wrote: "Happy 60th Birthday Madonna.

"You have haunted my dreams since I was 13. Shakespeare wrote about Cleopatra, 'Age cannot wither her, nor custom stale her infinite variety'. He could have been writing about you."

Madonna is the best-selling female recording artist of all-time with estimated sales of over 300 million.

She announced her first single for three years called Beautiful Game in May.
