Just three days before Disney releases the magical re-telling of Princess Aurora’s tale “Maleficent,” one ancestry site is claiming that the film star, actress Elle Fanning, is actually related to real British royalty.

According to a report from People Magazine Tuesday, the 16-year-old film star (sister to fellow actress, Dakota Fanning, 20), is cousins with Britain's Duchess of Cambridge, Kate Middleton, 32.

“The actress is the granddaughter of England’s King Edward III and also cousin of Kate Middleton,” reads the Ancestry.com report, conducted by historians via the family history resource site.

“Generation after generation, the lines we looked at pieced back directly to King Edward III proving that Elle is a direct descendant of royalty," Michelle Ercanbrack, a PR rep and family historian for Ancestry.com, told the magazine. "You can consider her a long lost princess. This connection is so unique and rare."

The report, which was created using 700 years’ worth of historical documents including both birth and death certificates, found that both Fanning sisters are connected to the former King through their mother, Heather Joy Arrington. Fanning, set to star as Princess Aurora in the “Maleficent” in theaters this Friday, is said to be the 22nd great-granddaughter of King Edward III, a five-decade-long ruler of England, who married Philippa of Hainault.

Fanning is also reportedly the 21st cousin of Middleton, the current wife of the Duke of Cambridge, Prince William. According to People, Middleton’s mom, Carole Goldsmith, is also a granddaughter to King Edward III, making Fanning a relative of the Duchess.

While there is no word what Fanning thinks of her newfound ancestral link, she has previously shared her excitement about portraying the animated Princess Aurora in the live-action film, “Maleficent.”

“Of course you dream of being a princess,” Fanning said during a behind-the-scenes featurette for the film. “I’m getting to play a princess which I never would have thought. I’ve had the best time and it’s really incredible.”
