At the X Factor house

- So, who is my duet with? I've heard George Michael's coming; is it him?!
- Ah, no.
- Well, I heard Robbie Williams is coming too- will I be singing with him?
- Um... no.
- Who then?
- Er, Michael Buble. He's massive in Canada.
- Oh. I won't pack a bag for Sunday night, then.
