Matronic's onstage flash

Scissor Sisters singer Ana Matronic was once left red-faced onstage when an ill-fitting costume and an energetic dance routine left her chest exposed for all to see.

The rocker insists she now picks her stage clothing carefully after making a boob of herself at the start of her career by inadvertently flashing the audience.

She tells InStyle magazine, "Usually, my costumes are pretty well built, but I was jumping up and down on stage once and a breast fell out of a bustier.

"Thank God I saw it in time and nobody caught it on camera. I never wore it again."
