A number of The Jump 2017 celebs have reportedly been struck down by a nasty illness while in Austria.
The stars who have signed up for the series, 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, Big Brother housemate Josie Gibson, 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.
According to The Sun newspaper, only Sir Bradley, Josie and Kadeena have escaped suffering a nasty stomach bug this week.
Emma Parker Bowles admitted: "My baby started it actually. She gave it to me. It was some kind of virus.
“It was actually someone in the kitchen that had it.
“Someone who worked in the kitchen. So it’s all the real dedicated breakfast goers that got it.”
Amy added to the tabloid: "We were all slowly getting knocked out. Less and less people were coming to training."
Still, we imagine they'd rather be ill at home rather than in hospital with broken bones like a number of celebs over the past three series of the show.
The Jump 2017 airs Sunday nights on Channel 4.
