Derek Hough & Bear Grylls on Running Wild with Bear Grylls (2018)

Season 4 of Running Wild with Bear Grylls is underway and Bear continues to recruit Hollywood hunks for his wild adventures. The fifth episode of the new season found Bear teaming up with television personality Derek Hough. Like his previous adventures with Zac Efron & Nick Jonas, this week's episode included some time in the water, forcing the guys to strip down for the occasion. Derek & Bear were left in nothing but their undies as they waded through a freezing stream.
