WATCH: Lenny Kravitz flashes crowd full-frontal as trousers split

Lenny Kravitz's trousers split open on stage on Monday, exposing himself to the crowd.

The 51-year-old rocker was left red-faced following his performance in Stockholm, Sweden, when his leather trousers ripped open along the crotch revealing he was wearing no underwear and showing his bare genitalia to thousands of fans.
