Tulisa is in a little bit of trouble at the moment, after using some swear words on stage at a festival in London over the weekend. Tulisa was doing a solo performance at Wireless festival and brought up her ex who sold her sex tape – she just can’t let it go can she. Most of us had slightly forgotten about that tape, but Tulisa just reminded us all about it. She was about to perform a version of Davis Guetta’s Titanium and decided to have a go at her ex. There were 60,000 people in front of her to witness it – including kids – but she still went off into a rant. We’ll say bleep where all the naughty words were. She 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.” Apparently Tulisa used that point to mention him as she thought that the words to the song she was about to do were very apt. A source said: "It was a spur of the moment decision. The crowd were totally behind her, all sticking up the middle finger to him." This is the second time within a week that Tulisa has been in trouble. When filming a video in London last week, she did a c sign with her hands – some thought she was copying the sign of a gang called Crime Scene Boys who have been linked to various crimes, but Tulisa claims she was just doing the c sign for Camden – where she is from. Tulisa didn’t seem to be worried about any of those events though after her performance. She hung out with the guys from JLS and then went and got a front row view to watch Nicki Minaj perform.
