Tulisa mellowing with age

Tulisa Contostavlos would have decked a mouthy contestant if she wasn't an 'X Factor' judge.

The N-Dubz singer, who is joined on the panel of the ITV1 show by Louis Walsh, Gary Barlow and Kelly Rowland, was subjected to a tirade of abuse by wannabe George Gerasimou during the London auditions, and admits she would have retaliated had it been 10 years ago.
