Not only is she one of the world’s most famous princesses, but Princess Diana had tons of famous relatives. And she’s not alone — many of the other British royals have fascinating celebrity relations, too.

For starters, Casablanca star Humphrey Bogart was Diana’s seventh cousin. “Lady Diana’s relationship to Mr. Bogart is a pretty remote linkup, but it is definitely there,” Hugh Peskett, senior genealogist of the aristocracy guide Debrett’s, once told UPI. And the late princess’s ancestry also links her to Little Women writer Louisa May Alcott, silent film stars Rudolph Valentino and Lillian Gish, financier J. Pierpont Morgan, and American World War II general George Patton. So cool, right?!

Plus, as TIME reported in 1981, Diana could count many world leaders as family members, including former British Prime Minister Winston Churchill. Across the pond, George Washington was Diana’s eighth cousin seven times removed… and he’s not even the only American president related to her! Through the “wife of an eccentric American great-great-grandfather,” Lady Di was reportedly related to Presidents John Adams, John Quincy Adams, Calvin Coolidge, Millard Fillmore, Rutherford B. Hayes, Grover Cleveland, and Franklin D. Roosevelt. And, she and George W. Bush are 11th cousins twice removed.

Now, on to those other royals. Did you know Beyoncé and Queen Elizabeth are actually relatives? Sure enough, Beyoncé and Elizabeth are 25th cousins once removed, according to Vogue, while Johnny Depp is a 20th cousin of the Queen. Now we just have to rethink that line of succession to see how far down these stars are!

Meanwhile, singers Madonna and Céline Dion are both related to Prince Charles‘ wife, Camilla Parker-Bowles. Madonna’s ex Guy Ritchie, on the other hand, is a sixth cousin of Kate Middleton — which is likely how he scored an invite to her wedding — while Ellen DeGeneres is a 15th cousin of Kate. And Harry Potter actor Ralph Fiennes is an eighth cousin of Charles.
