WATCH Mylo's BIG mistake at the Star Wars Premier
Mylo's not seen any of the Star Wars films but was invited by the Odeon cinema Leeds Bradford to see the brand new The Force Awakens.
Rosie told him that Star Wars fans are proper "hard core" and in order to fit in, he must dress up as a character.....
Now because Mylo doesn't actually know any of the characters he stupidly trusted Rosie in picking the costume for him.
MUHAHA (Evil Rosie laugh).
