X Factor judge Tulisa is top of the singles chart with her solo hit, Young.

The track, written by fellow N-Dubz member Fazer, knocked Canadian singer Carly Rae Jepsen into number two.

She was a member of N-Dubz along with Dappy her cousin, and Fazer her ex-boyfriend.

The band put their work on hold last year when Tulisa got her judging job on X Factor.
