Iggy Azalea Lets Fans Smack Her Bare Ass During Performance

Fan smacking Iggy's ass on-stage in Amsterdam.

Grand Hustle's Iggy Azalea isn't scared to be overly sexual or over-the-top ... even during performances.

The Australian bombshell is currently on tour, and during one of her stops in Amsterdam, she got up close and personal with a fan, pulling up her cheerleader's skirt and letting them smack her ass. Woah!
