Sunday night's guest line-up revealed

It's only Tuesday and we're already getting X-cited for the weekend as the guest artists performing on the Live Results Show have been announced. *Drum roll please.*

Sunday night's guest line-up revealed

This week, we're getting not two, but THREE acts coming to strut their stuff. Uh-maze.

Coming all the way from America are the silky-voiced Bruno Mars who loves us just the way we are, and rocky pop chick Kelly Clarkson - showing our finalists just how mahoosive a talent show can make you.

And for all you hip hop-sters out there, Professor Green is also taking to the stage.

Put yo' hands up if you can't wait! Woop woop!
