The barmaid from Dudley is hoping for her second shot of fame, and admits: "This isn't the first time in the limelight so I'm scared."
But with the likes of Five star Sean Conlon and MOBO winner Allyson Brown already being turned away, it's only the best that will make the cut.
There's just nine spots left on the teams going into this evening's final show, with Jessie J, Sir Tom Jones and Danny O'Donogue all after two artists each, while picky Will.i.am wants three.
Will any of them turn around for Jenny?
