And, Davina McCall has opened up about some of the most shocking injuries from the previous run, admitting the crew were left "horrified".
Speaking about the moment she found out Olympic gymnast Beth Tweddle has dislocated her neck before the live show had begun, she admitted: "We were all horrified.
"At the same time Beth was injured, there was a massive avalanche with about 12 fatalities, and none of us knew what was happening to Beth because there were a lot of people who were critically injured, so we didn't hear for ages.
"We were going live that night and I didn't know what to say. I ended up saying something like: 'Beth has had a routine operation,' which for a dislocated neck sounds quite glib."

We were all horrified
Davina added: "But, I was told by the doctor to say that because to them, it is a very routine operation. They do 200 of them a year. But obviously it's a big injury.
"All our hearts sank – Beth was one of my favourite contestants ever. She couldn't have been kinder or lovelier to work with."
The Jump host told The Sun: "We were gutted for her and her family to go through all that worry. But thank God, she was okay."
This year's series has already been plagued with injuries. Earlier this week, it was revealed that Vogue Williams was forced to pull out after sustaining severe damage to her knee.
