Lydia Bright has become the latest name to sign up for The Jump 2017 line up.
The star of The Only Way Is Essex confirmed the news in a picture online alongside previously confirmed contestant, Made In Chelsea's Spencer Matthews.
Lydia quipped: "Reality show down, Chelsea Vs Essex @SpencerMatthews #TheJump 🎿 ⛷ @Channel4"
Also joining the pair on The Jump 2017 line up is Vogue Williams.
Model Vogue previously took part in Bear Grylls: Mission Survive - which she won - proving herself to be more than up for an extreme challenge.
Vogue said: “I’m thrilled to be taking part in The Jump as it’s a show I’ve wanted to do for years! I love winter sports, so I can’t wait to put my ski boots on and hit the Austrian slopes.
"It’s going to be so much fun and I’m looking forward to a bit of friendly competition with the other celebs!”
The trio join footballer Robbie Fowler and model Caprice Bourret on the cast of next year's show.
Meanwhile, two rugby stars have also been confirmed for the winter sports contest: former England captain Jason Robinson OBE, and Welsh international Gareth Thomas.
The rest of the line-up will be announced in due course, with presenter Davina McCall recently teasing that it's "unbelievable".
This year's competitors may be some of the bravest names in showbiz after the last series proved a disaster, with seven celebs withdrawing due to injury.
Despite the nightmare, C4 announced a fourth series of The Jump in July, following a "thorough review of safety standards".
The Jump 2017 will air on Channel 4 in the new year.
