At her Istanbul concert on Thursday night, the 53-year-old singer flashed a lot of skin, but she didn't have a wardrobe malfunction.

While performing her hit 1995 song "Human Nature" the singer began stripping off her clothes, first removing her white shirt, before she simply pulled down her bra to give the audience a good look at her right nipple.

The singer, who took the stage at the Super Bowl's halftime show in February, assured "The Tonight Show" host Jay Leno days prior to the game that "for sure [there'd be] no nipples" during her routine, so perhaps Madge was just itching to pull hers out in Istanbul?

It's not as if we haven't seen Madonna's nipple -- or for that matter just about every part of her body -- before. Her breast flashing antics are clearly designed to titillate but, frankly, we're over it.

The singer/actress/director and mother of four has been doing her best to cause controversy on her MDNA tour.

She recently enraged the French National Front leader Marine Le Pen, during her show in Tel Aviv, Israel, when she performed the song "Nobody Knows Me" in front of a giant screen showing Le Pen with a swastika on her forehead.

The image appeared only for a split second in a montage featuring the likes of Sarah Palin and Chinese president Hu Jintao. However, the photo apparently caused enough of a stir for Le Pen to consider suing. According to the Daily Mail, Le Pen has threatened legal action should Madonna continue with the performance in France.

Le Pen is the head of France's National Front, a far-right political party that has been accused of racism.

"We are not a Nazi party, and object to being depicted as such," a party source reportedly told the Daily Mail.
