Grungy Kesha reveals her bruised and battered legs in punk inspired outfit

It may have made her a star, but Kesha's aggressive stage style can be a bit of a pain.

The young singer revealed her painfully bruised legs in a pair of shorts yesterday, surely a casualty of the nights she spends rocking around during her world tour.

The 24-year-old is known for her punk-style choreography, throwing herself around stage wearing little more than a pair of fishnets to protect her legs.
