Diamonds may be a girl’s best friend. But Marilyn Monroe and Sydney Sweeney? It turns out they’re actually cousins.

Ninth cousins, once removed, to be exact, according to MyHeritage.com.

“People have always drawn parallels between Sydney Sweeney and Marilyn Monroe, but seeing their paths align on a deeper level inspired us to look for a real bond in the MyHeritage archives,” Roi Mandel, director of research for the genealogy site, stated in a recent press release. “Uncovering their shared branch was incredible, it’s a powerful reminder that humanity is one vast family tree, and when we dig deep, we uncover how remarkably interconnected we all are.”

While Sweeney has yet to publicly comment on the family connection, she has channeled Monroe in the past.

In February, for instance, the Euphoria actress walked the red carpet at the Santa Barbara International Film Festival in an off-the-shoulder, cream Ceil Chapman gown—a dupe of the frock the late Hollywood icon wore on the cover of LIFE Magazine in 1952. And when Sweeney attended the L.A. premiere for her film adaptation of The Housemaid in December, she wore a white halter gown by Galia Lahav that brought back memories of the famous William Travilla dress Monroe wore in her 1955 movie The Seven Year Itch.
