Madonna has posted a reminder on her 60th birthday that she is still the Queen of Pop.

The 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”.

The American singer-songwriter 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 to Madonna.

He wrote: “#JoyeuxAnniversaire to my long time friend, my everlasting muse and our Queen of Pop Madonna.”

Singer 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!”

Little Britain star and Britain’s Got Talent judge 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 with her, not custom stale her infinite variety’. He could have been writing about you.
