Former 'X Factor' contestants like 'best friends' to Scherzinger

Nicole Scherzinger has said that her former 'X Factor' contestants are like "best friends".

The 34-year-old singer has revealed her final three boys from last year - Jahmene Douglas, Rylan Clark and winner James Arthur - are still very close after having formed a bond and while she still helps them out in times of need, Nicole knows they are responsible enough to not worry about.
