Some people wait a lifetime for a moment like this but being honest, we aren't exactly over the moon at the thoughts of another evening with Leona Lewis. That said, Michael Buble is performing live on this week's X Factor results, so we're more than happy to tune in to see the Canadian king of swing doing this thing. Oh, and then there's the whole Semi-Final elimination thing. We'll know who's in the X Factor final by the end of the night sure.
