Katie Hopkins dresses up as Boris Johnson - and other funny celebrity transformations

This week, Katie Hopkins got the chance to dress up as her 'Loud Icon' Boris Johnson to help raise money for Global's Make Some Noise charity. In celebration of her funny transformation, we've rounded up some more celeb 'makeovers' - take a look!

Taking part in the same campaign as Katie is Jamie Theakston, who chose to appear as rock icon Freddie Mercury.

"Freddie would have been 70 this year and chances are he would still be with us if he hadn't died just two years before breakthroughs in treating HIV," he said.  

"Dressing loud is all about expressing yourself to help others and no one did that quite like him.  It wasn't easy trying to recreate his iconic look – there was no one else quite like him and I don’t think there ever will be.  I think I look more like a tall Manuel from ‘Fawlty Towers’ or someone auditioning for a Queen tribute band than Freddie.  If, by making a fool of myself, it means that just one small charity gets a chance to assist someone who needs their help, then that’s time well spent!"

Vernon Kay meanwhile, transformed into The Doors frontman Jim Morrison. 

"The Doors was the band that I first fell in love with and when I was in sixth form it provided the soundtrack to my student days" he said. 

"Jim Morrison was a true icon – both musically and visually.  He was outspoken and one of those rock stars in the 27 Club who will never be forgotten.  

"Dressing up as him was an honour and also quite a liberating experience – I’ve never worn leather trousers before and I’ve always wanted to give it a try!  I’m really happy to be part of Global’s Make Some Noise which helps young people who are struggling."
