Tulisa was involved in another scandal this year after it was suspected that her trademark arm gesture - which showed her tattoo reading The Female Boss - was a bid to advertise her perfume of the same name.

Like Cheryl's trademark salute, every week Tulisa would show the tattoo on the X Factor stage.

OfCom are investigating whether was is classed as illegal advertising, but in retaliation the week after the claims, Contostavlos wrote Vote Little Mix on her other arm.
