X Factor 2015: Watch husband and wife duo Nige & Kay wow judges

Duo Nige and Kay wow the X Factor 2015 judges this weekend with their audition.

Kay Wilson 26 and Nige Wilson 44 first get mistaken for brother and sister by the judges ahead of their performance.

They're quick to correct the panel, telling them that they are in fact a husband and wife duo from Scunthorpe.

Currently working as a builder and retail assistant, Nige and Kay sing Olly Murs and Demi Lovato's Up for the panel.

"This guy sings it better than me!" remarks Olly from the sidelines.

Other acts who appear on this week's final audition shows include Blackpool Paul, who duets with Olly Murs on stage.

There's also Ice Cream Andy, who's audition turns into a right mess quite literally, and Welsh mum Sherilyn Hamilton Shaw who leaves Cheryl emotional with a Whitney Houston cover.
