The singer was snapped making the gesture whilst filming her new video in the Church End area of London.

The 'C' symbol is linked to the area's Crime Scene Boys group - but The Sun reports that Tulisa has issued a statement to say that she made the gesture in tribute to her home town Camden. She said:

"I filmed a street video on Sunday night for a track on my album. The video was a collaboration with the rapper Nines. When we were filming on the street loads of other people turned up and joined in the shoot."

Tulisa continued: "When I was holding my hands in the C sign, this was as a tribute to Camden, my home town and where N-Dubz began. I am not aware that this sign has anything to with any street gang and I 100 per cent do not endorse any gang violence in any form."
