X Factor final 12th December: Olly Murs and Robbie Williams sing 'Angels'

Olly Murs looked visibly nervous when he tok to the stage tonight as he waited for Robbie Williams to appear.

He handled the vocals well on his own but then Robbie took to stage.

Ok, before we start this and all you Robbie lovers blast me, I LOVE Robbie Williams. But when he took to the X Factor stage tonight, he did cock up on a major level.

As he emerged onto the stage, to join Olly in a rendition of Angels, he missed his cue and for the rest of the song he looked close to tears. Olly Murs looked like he was going to crap himself!

There definitely wasn't the professionalism that was visible during Stacey Solomon's routine with Michael Buble, but there was a great rapport. I hope the mistake won't cost Olly his place on tomorrow night's show.
