MADONNA EXPOSES BREAST DURING ISTANBUL CONCERT

At her concert in Istanbul Thursday, Madonna performed a sexy striptease while singing her 1995 hit, "Human Nature." The 53-year-old started off the tune in a menswear-inspired white button-down and pinstripe slacks. Once her song got underway, the Material Girl stripped off her shirt, revealing the lacy, strappy black bra she had on underneath.
