The former rugby professional – who is married to The Queen's granddaughter Zara Phillips – is the first famous face revealed to be competing on the Channel 4 reality competition.
A spokesperson confirmed the royal family member's appearance today, saying the "ink is literally drying on the contract."
Mike, 36, will follow in the footsteps of X Factor's Joe McElderry, singer Sinitta and TOWIE's Amy Childs in taking on the TV show challenges.
The Jump tasks celebrities with learning and the competing in dangerous winter sports. It will return to Channel 4 for a second series next year, filmed in Innsbruck, Austria.
While we don't think The Queen will be jetting out to Austria to support him from the sidelines, we wouldn't be surprised if Zara Phillips and baby Mia were spotted cheering him on!
