Madonna

Wardrobe malfunction? Not exactly.

Madonna flashed her right breast during a concert in Turkey last Thursday, and it was definitely no accidental nip slip.

The 53-year-old Material Girl turned her performance of "Human Nature" into a striptease when she took off her shirt and then pulled down the front of her bra, exposing her right nipple.

This was not the first attention-grabbing antic Madge has pulled on her MDNA Tour. Two weeks ago, she performed a mash-up of "Express Yourself" and Lady Gaga's "Born This Way" to show the similarities between the songs. During her concert in Tel Aviv, a swastika was emblazoned on the forehead of right-wing French leader Marine Le Pen in a video; Le Pen's National Front party has been accused of anti-Semitism. Le Pen later threatened legal action if Madonna were to pull the stunt in France.
