The 'Made in Chelsea' star, 27, has become the fourth celebrity to pull out of the dangerous winter sports show after he snapped his ankle while battling it out in the aggressive Snow Cross challenge in Sunday night's episode (07.02.16).

A spokesperson for Channel 4 said in a statement: "Whilst racing during the show on Sunday evening, Mark-Francis fell, injuring his ankle. He received immediate medical attention but sadly will not be able to continue in the competition due to an ankle fracture which has now been treated."

The posh boy sparked speculation he'd undergone surgery earlier this week when his fellow contestant Brian McFadden uploaded a photograph of him in a hospital bed on Instagram.

Alongside the picture, which has since been deleted, the former Westlife singer wrote: "Even post surgery MarkVandelli looks like a Versace model!!! (sic)."

Meanwhile, Mark's injury came just a day after Beth Tweddle, 30, was airlifted to hospital with a broken back after she ploughed into a barrier and landed awkwardly on her spine.

'Holby City' actress Tina Hobley, 44, was also forced to pull out last week after she dislocated her elbow and fractured her arm when the crew failed to vacate the landing area.

And Olympic swimmer Rebecca Adlington, 26, has decided to depart the competition after she dislocated her shoulder while practicing the frightening air jump the week before.
