'Chains' hitmaker Nick Jonas has been confirmed to take part in Bear Grylls' forthcoming adventure series. 

Grylls, who recently teamed up with President Obama for an episode, takes celebrities out into the wilderness and puts their survival skills to the test. Nick Jonas will join him in Sierra Nevada for a special expedition. 

Jonas, meanwhile, has now unveiled his music video for 'Chainsaw' and told his followers that it means a lot to him: "This was the first video we shot for the album and the closest to my heart."

As previously reported, Jonas told Out magazine that trying to date as a celebrity is very difficult: "It definitely sucks. It sort of feels like, on top of dealing with the situation with the person, you have to be thinking about other people’s opinion about it, and without all the information."
