PEOPLE can exclusively reveal that Jonas, 23, will guest-star on the premiere this August when the star-studded outdoor adventure series returns with a spectacular, two-part season 3 opener.
The singer can be seen huddling in the snow of the Sierra Nevada Mountains as he and Grylls trek through icy cliffs and avalanche-prone mountains. And we’re only a little “Jealous” of Grylls for getting to behold a shirtless Jonas as they splash through freezing waters.
Hough, 27, opted for more of a warmer climate and is seen accompanying Grylls on an African Savanna as they adventure through cliffs and canyons, coming into contact with a few safari animals along the way.
