Tulisa Contostavlos - Tulisa Contostavlos Slams Sex Tape Ex During Festival Set

The N-Dubz star was devastated in March (12) after explicit footage, which showed her performing a sex act on ex-boyfriend Justin Edwards, hit the internet.

Contostavlos subsequently insisted the scandal had made her stronger, but she used her set at the U.K. capital's Wireless Festival in Hyde Park to take aim at Edwards.

She told the crowd, "Put your middle fingers up to my d**khead ex, Justin f**king Edwards! Ladies, don't ever let any man pull you down, because I'm still f**king standing."

A source tells Britain's The Sun: "It was a spur of the moment decision. The crowd were totally behind her, all sticking up the middle finger to him."
