London, October 27 Singer Amy Winehouse shocked onlookers when her breasts busted out of her top.

The Rehab hitmaker, who recently shelled out 35,000 pounds on a breast enhancement surgery, was snapped as her new 32D chest slipped out of her flowery corset.

The 26-year-old's wardrobe malfunction was said to be her second slip-up after she failed to turn up on time at an awards bash earlier, reports the Sun.

Amy was due to present a trophy to The Specials at the Q Awards at London's Grosvenor House Hotel.

But the star went missing during the time and later appeared on the stage just as the band was leaving. (ANI)
