ITV has confirmed this afternoon, May 30, the final line up of the X Factor's new judging panel. 

After months of speculation, it has finally been revealed that N-Dubz's Tulisa Contostavlos and Kelly Rowland will join Gary Barlow and Louis Walsh as judges on the popular talent contest. 

Peter Fincham, ITV's Director of Television, said of the announcement:

"As multi-million selling artists, songwriters and pop masterminds, Gary, Tulisa, Kelly and Louis have huge breadth of appeal with our audience and the ability to engage both the UK’s next generation of music talent as well as ITV’s viewers."
