SYDNEY Sweeney has discovered she is related to fellow blonde bombshell Marilyn Monroe.
The Housemaid and Euphoria actress’s family tree reveals she is a ninth cousin once removed of the Hollywood icon.
Researchers found the stars’ fathers were both descendants of a Massachusetts settler called Ezra Perry who died in 1689.
Sydney, 29 — who starred in a controversial advert for American Eagle with the tagline Sydney Sweeney has great jeans — has often been compared to Marilyn, born Norma Jeane Mortenson.
She had huge hits with movies such as Some Like It Hot, Gentlemen Prefer Blondes and The Seven Year Itch.
The research was carried out by MyHeritage.
Spokesman Roi Mandel said: “People have always drawn parallels between Sydney and Marilyn Monroe.
“Uncovering their shared branch was incredible.”
The startling discovery is bound to excite Sydney, who has worn several outfits similar to ones sported by Marilyn.
In February she wore a vintage dress inspired by the late Hollywood icon to the Santa Barbara International Film Festival.
The slinky Ceil Chapman design was startlingly similar to one which Marilyn wore on the cover of Life magazine in 1952.
