Watch Dermot O’Leary become Game Of Throne’s Jon Snow (and Steph and Dom from Gogglebox AND Sherlock!)

There are many reasons why we love X Factor host Dermot O’Leary (The dancing! The spinning! The suits!) but one of the biggest is that the man LOVES to dress up.

For the fifth year in a row, Derm will be hosting this year’s National Television Awards (on 21 January, TV fans) and as is tradition he agreed to pay homage to three of this year’s nominees – Game Of Throne’s Jon Snow, Gogglebox’s Steph and Dom and Sherlock.

Check out our exclusive behind the scenes footage from the shoot and see Derm giving his best smouldering look as Jon Snow and how much he looks like Katie Hopkins when he's dressed as a woman.
