Spice Girl Mel B is back - yaaaaay. Her claws rejoin Gary Barlow, Tulisa and Louis Walsh at the Manchester auditions, while Nicole Scherzinger is with the panel in London and Newcastle. Expect the usual mix of enthusiasts with limited talent, those who are gifted but lack confidence, the completely tone-deaf whose every note is a trial - and the surprise packages who make it all worthwhile. Dermot O'Leary shares the audience's pleasure - and pain - and provides a suitably caustic commentary on the contestants' efforts. The Xtra Factor follows on TV3 at 9.15pm while Red or Black? gets another turn on UTV at 9.00pm. Ant and Dec will be joined by Little Mix - 'cause Simon Cowell just can't help himself.
