HOLLYWOOD icon Clint Eastwood is devastated over his wild-child daughter Francesca’s quickie Las Vegas wedding, sources say.

The 20-year-old blonde got sober after a rehab stint in 2012, but her fa­mous pop’s impending divorce, along with her split from a longtime boyfriend, triggered a stunning relapse, according to an insider.

And it all came to a head when she eloped with music manager Jordan Feldstein to the Simple Wedding Chapel after a drunken night on the town, the insiders add.

“Francesca is on a downward spiral of booze and painkillers after cleaning herself up last year,” revealed a family friend.

“She’s very close to her stepmother Dina, and there’s no question that the divorce battle between Dina and her dad is bothering her.

"On top of that, she’s rebounding from a painful breakup with her pho­tographer boyfriend Tyler Shields. Her crazy weekend in Vegas was a cry for help!”

An Elvis impersonator was on hand when Francesca – whose mom is actress Frances Fisher – walked down the aisle with Feldstein, brother of actor Jonah Hill, on Nov. 17.

Four days later, Francesca – Miss Golden Globe 2013 and star of the reality TV show “Mrs. Eastwood & Company” on E! – stepped out in public without a wedding ring, and family sources put out the word that she was seeking an annulment.

“Francesca woke up the next morning and regretted it,” said the source.

Another family source added: “Clint, Dina and Franc­esca’s mom were all terribly upset over the wedding.

“Francesca had been healthy and they all want to see her stay sober. But they know she’s coping with a lot right now, and they’re all there for support.”
