Jessica Alba and Cash Warren‘s marriage hasn’t just hit a rocky patch, they’re about to call it quits with a divorce filing … TMZ has learned.

Sources with direct knowledge tell TMZ … the couple recently separated, and they’re moving forward with divorce. It’s unclear what brought them to the decision to end their nearly 17-year marriage, but there have been some public signs of trouble.

Both Cash and Jessica have been out and about without their wedding rings. Most recently, she attended a pre-Golden Globes party Saturday at Chateau Marmont in West Hollywood without Cash, and without her ring.

Ditto for her night out in Rome last month with film producer Andrea Iervolino — no wedding ring on her hand as she and Andrea were beginning to work on the biopic, “Maserati: The Brothers.”

For his part, Cash was out and about in L.A. last week with a ring-less left hand.

The last time Cash and Jessica were photographed together was at L.A.’s Crypto.com Arena back on November 10 as they sat courtside for a Lakers game. Jessica also posted a family photo from Universal Studios last week, though it’s unclear if was a current photo or a throwback.

The estranged couple met in 2004 on the set of “Fantastic Four.” She was starring in the movie and Cash was working as a director’s assistant. They got engaged in 2007 and then married a year later with a low-key Beverly Hills courthouse ceremony.

They share 3 children … 16-year-old, Honor, 12-year-old Haven, and 7-year-old Hayes.

How this divorce plays out will be interesting … Jessica’s had tremendous success, launching a billion-dollar brand with The Honest Company. We do not know if they signed a prenup.
