It started off with the twosome singing Something Stupid together.
Holly chose Cindi Lauper's Girls Just Wanna Have Fun for her solo, and Jake sang Robbie's She's The One.
The panel of judges was a bit different from usual. It featured Peter, who'd just been expelled, CBBC's Fearne Cotton, as well as regular judges Robin Gibb and Richard Park.
Holly won a car
Head teacher Richard was quite nice to Holly, and actually said she wasn't bad at all!
Although Holly didn't get a record contract or luxury flat for winning, she did get a car - even if it was remote controlled!
