Happy Birthday, Madonna! The Material Girl’s 22 Most Controversial Moments (PHOTOS)

Happy birthday to the Queen of Pop!

Madonna turns 54 today — but the singing superstar shows no signs of slowing down. After a few years out of the spotlight, Madonna made a comeback in 2012, dropping a new album and launching a world tour.

All the while, stirring up trouble, of course.

Madonna is no stranger to controversy. From flashing her breasts, to burning crucifixes, to kissing Britney Spears, to bearing arms on stage, the Material Girl is notorious for her out-there antics.

With her worldwide MDNA tour, the pop icon has been causing plenty of commotion as of late.

Kicking off tour in front of a sold-out crowd in Tel Aviv, Israel, Madonna raised eyebrows when she wielded (faux) fire arms on stage — even whilst pleading for world peace.

And while on stage in Istanbul, Turkey, the Queen of Pop flashed her bare breasts. Just a few days later, Madonna showed off her rear during her Rome show.

So, in honor of Madge’s 54th birthday, Celebuzz is chronicling her most notorious and talked-about controversies.
