Maleficent star Elle Fanning has expressed her shock at being distantly related to King Edward III and the Duchess of Cambridge, Kate Middleton.

The 16-year-old actress, and her older sister Dakota, are reportedly the descendants of King Edward III who ruled in England in the 14th century, and ancestor they share with future Queen, Kate Middleton.

Speaking to E! Online, Fanning said: "It's so weird. I saw it the other day. My cousins called me up and they were like, 'Look online'. I looked online and like, King Edward III is my great-great-great-grandfather. I was like, 'Is this real?' It's crazy."

Fanning added: "I've always wanted to do the thing because I think it would be really cool, but someone did it for me, which I think is great."

Maleficent is in cinemas now.
