Tulisa has already recorded a video explaining the details of their relationship and apologising to fans after the sex tape leaked, but her on stage rant at Wireless was seriously angry.
Tulisa said: "Put your middle fingers up to my d***head ex, Justin f****** Edwards! Ladies, don't ever let any man pull you down, because I'm still f****** standing."
However, despite much of the crowd supporting Tulisa, some onlookers weren't impressed that she decided to rant so explicitly on stage at 3 in the afternoon. Eek.
During a video shoot earlier this week, Tulisa was snapped making the C symbol with her hand - a known gesture by the Crime Scene Boys, a gang linked to drug and gun crime.
Tulisa was forced to defend herself, saying that the gesture was a reference to her hometown of Camden.
Well, Tulisa's nothing if not fiesty. After her rant about her sex tape ex boyfriend, Tulisa gave an amazing performance at Wireless Festival.
The star was dressed in a cleavage revealing patterned top and matching skirt. Gorge.
