Lily Allen was left stunned following a gig in Manchester, England earlier this month (Mar10) - after a cheeky fan pulled down his pants and exposed his bare behind.
The Smile hitmaker had stepped off the stage after a show in the city on 5 March (10) and was heading back to her hotel when a young male approached her.
And Allen got more than an autograph request from the man, when he pulled down his jeans and flashed his bottom at the singer.
The star's security ensured Allen wouldn't have to witness the sight for too long, covering her eyes with her Chanel handbag to save her any embarrassment.
