Holly Willoughby says new co-host Lee Mack is the 'funniest' person she's worked with

Holly Willoughby is normally to be found nestled in a warm TV studio in London but that all had to change for her latest showbiz gig.

For her new series, Freeze the Fear with Wim Hof, Holly braved the sub-zero temperatures of the Northern Alps.

Though unlike the eight celebrities taking part in the chilly challenges, she remained wrapped up, dry, and fully glamorous at all times.
