The Essex reality star and beautician will learn some of the most dangerous and challenging winter sporting disciplines for the brand new Channel 4 series, to air early next year.
Amy will be competing against 11 other brave celebrities including 80s songstress Sinitta, former Pussycat Doll Kimberly Wyatt, socialite Tara Palmer-Tomkinson, broadcaster Anthea Turner and TV presenter Melinda Messenger.
Joining them will be five time Olympic gold medallist Sir Steve Redgrave, ex-England cricket legend Darren Gough, comedian Marcus Brigstocke, celebrity hairdresser Nicky Clarke, socialite Henry Conway, and Sam Jones, who is better known for his iconic role in Flash Gordon.
Davina McCall will present the new reality show alongside Alex Brooker. Davina said: "Skiing is tough enough to learn as it is, so what these guys are taking on is really impressive - it's shaping up to be butt-clenchingly exciting!"
Show bosses say the 12 celebrities will need "nerves of steel" as they compete in some of the most terrifying winter sports including Skeleton, Bobsleigh, Speed Skating, Skier Cross and Slalom.
They will be put through their paces by Winter Olympic skier Graham Bell and Winter Olympic Skeleton gold medallist Amy Williams, as well as legendary Winter Olympian Eddie 'the Eagle' Edwards.
Each night, two of the celebrities will face a live ski jump to keep their place in the competition.
"This competition is as much about mental strength as it is about physical agility," said Eddie. "Winter sports are tough to master; it takes skill, guts and determination to get round a course. The ultimate test will be The Jump itself. I know how hard it can be when the world is watching."
The Jump is expected to air on Channel 4 for 10 nights in early 2014.
