The Jump 2017 celebrity contestants have reportedly angered show bosses by breaking a safety booze ban.
The stars who have signed up for the series this year are Made In Chelsea's Spencer Matthews, TOWIE's Lydia Bright, model Caprice Bourret and Olympic gymnast Louis Smith.
More celebs on The Jump this year are rugby player Gareth Thomas and Paralympic medallist Kadeena Cox and retired pro cyclist Bradley Wiggins.
Others on the cast are Footie player Robbie Fowler, Olympic taekwondo champ Jade Jones, rugby player Jason Robinson and comic and TV host Mark Dolan.
Rounding off the line up are model Amy Willerton and Camilla Parker Bowles’ niece Emma Parker Bowles.
Ahead of Sunday night's latest live show, Spencer complained to the Daily Star newspaper: "There is no wine or anything for us before we hit those slopes.
"We are under strict instruction, with all the health and safety nonsense."
However comic Mark admitted that the ban hadn't been fully enforced.
He told The Sun on Sunday newspaper: “We’ve brought the athletes down to our level — the wrong food, not enough sleep and lots of alcohol.
“There’s been loads of boozing. There was an email about it which has been promptly ignored — it was a duty of care thing."
He explained: “Channel 4 don’t want injuries. They’d like this to be the series with the fewest injuries. And it’s been mentioned we shouldn’t have late nights and drink too much.
“In fact, we were told in explicit terms, if you’re hungover or still drunk, you’re not training."
So far The Jump has lost two contestants after one show with model Vogue Williams forced to quit before the launch due to injury.
Big Brother housemate Josie Gibson became the first celeb to be evicted in last Sunday's first live episode when nerves got the better of her and she REFUSED to jump.
The Jump 2017 is back tonight with the latest show at 7:30PM.
