Emilia Clarke once tricked her 'Game of Thrones' cast mates into thinking she had a birth mark on her face after she accidentally burnt herself on curling tongs.

The 31-year-old actress has admitted she managed to fool her co-stars into thinking she'd always had a pink mark on her face after she rocked up to the show's wrap party once with a painful burn mark following a failed hair style.

Speaking to Harper's Bazaar magazine, she said: ''I'm good at doing my own make-up; terrible at doing my own hair. Can't do it to save my life. Never have been, never will be. I had a book of hairstyles when I was aged nine that my mum got me, that was like 'how to do a French braid' and months and months I poured over that book - and I can't do it.

''If I try and curl my own hair I burn my face or my ears, I'm hopeless. I recently burnt my face before the 'Game of Thrones' wrap party and everyone was like 'we never noticed that massive birth mark on your face!' and I was like, 'no, it's a burn...' I had my head under the tap for about three hours!''

Emilia takes her beauty regime very seriously but she doesn't believe in a whole cabinet of lotions and potions and, instead, relies on a silk pillow that she flips every night to ensure her pores don't get clogged and her hair stays frizz-free.

She explained: ''I do the silk pillows. Because that's easy. They're not any more expensive than normal pillow cases. They actually aren't.

''And make sure they're clean! A lot of us are lucky and we like to sleep in a double bed - so let's say you have four pillows; one night you sleep on one side, the next night flip it over the other side, the next night do the same with the other pillow - and that way you've got a weeks' worth of clean pillow case against your skin! And if you ever have frizzy hair problems, sleeping on a silk pillowcase really helps that too. It really makes a difference.''
