Former X Factor winner Joe, 22, had been on standby to join the C4 show and was awarded a spot after competitor Henry Conway broke a finger.
Earlier today, Joe joined fellow X Factor favourite and Jump contestant Sinitta, along with standby Donal McIntryre, in a morning ski session.
The trio hit the slopes and skiied to the Jump's snowy Austrian studio before taking part in some filming ahead of tonight's show (29 January).
Sharing a picture on Instagram, Joe said: "Fun ski down to jump studio. After speed ski filming! @sinittaofficial @donalmcintyre."
Joe won his place in the show after going head-to-head with investigative journalist Donal on a ski jump.
Both opted for the programme's medium jump, but Joe cleared a distance of 15 metres while Donal only reached heights of 11.5 metres.
Last week, Joe shared a picture of himself after he'd slipped over on the ice while training. Oops!
