Micahel Buble has been confirmed as the second guest performer on this Sunday's X Factor.
The Canadian singer will return for his third outing on the reality show, following performances in the 2007 semi-final, the 2009 Big Band week and a 'Feeling Good' duet with Stacey Solomon in last year's final.
Earlier this week, it was confirmed that Cheryl Cole will also be playing 'Promise This' from her upcoming Messy Little Raindrops album.
The X Factor results show airs on Sunday at 8pm on ITV1.
