Move over, Prince William!

Johnny Depp might have royal blood, too. Genealogist Nick Barratt says that the Pirates of Caribbean star shares the same distant blood line as the royal family.

The 47-year-old actor has the same great, great, great, great, great, great, great, great, great, great, great, great, great, great, great, great, great, great, great-grandfather (that’s 19 greats) as Queen Elizabeth, 85. That makes the Hollywood star and Her Majesty 20th cousins.

Dr. Barratt tells the Sunday Mirror: "You have to back more than 500 years to reach the point where [Depp's] ancestors become royal."

Depp was born in Owensboro Kentucky in 1963; his immediate ancestors were farmers who settled in Virginia in the 1700s and traded with American Indians.

"I believe the balance of probability is that there is indeed a link between Depp and the royals," Barrett explains. "[Although] I doubt we'll ever be able to prove it 100 percent."
