Famed for his survival skills and all-round adventurist attitude, Bear Grylls is no stranger to danger. So it made sense, then, that the only way he could enter the studio of ITV's This Morning, was to smash through the window.

The TV star landed a speed boat on the shore of London's Southbank – along with a couple of marines for good measure – shimmied up several stories-worth of rope and then came crashing feet first through the studio window. Not happy with just smashing the window, he also broke a few flower vases in the process.

Bear – real name Edward – is leading eight celebrities into the Central American rainforests for a 12-day survival mission.

The show Bear Grylls: Mission Survive will see the celebs really pushed to the limits.

Loose Woman presenter Jamelia has already revealed that she clashed with Laurence Fox while filming.

The show starts on ITV on 20 February.
