John Schneider has found a new Duchess of Hazzard — tying the knot with Dee Dee Sorvino, widow of the late Paul Sorvino … about two years after his own wife passed.

The “Dukes of Hazzard” star and Dee Dee exchanged vows in Las Vegas Tuesday night — with sources telling us they got hitched at the Vegas Weddings venue in Sin City … with the couple driving away in a convertible that was once owned by Usher.

We’re told Schneider and Sorvino are planning a reception in L.A. — which will go down at the Hollywood Museum on August 1 … the place they first met.

Like we mentioned, this ain’t the first wedding for either star … ’cause they were both in loving relationships before their respective partners recently passed away.

Schneider’s wife Alicia Allain, 53, died last year after a battle with breast cancer … just three years after marrying John.

As for Paul — best known for his roles in “Goodfellas” and “Romeo + Juliet” – he died the year before from natural causes after fighting a series of health battles over the years.

JS revealed he was dating a new person in May during an episode of “Grace Begins, The Podcast” … explaining God sent him a fellow widower because he needed someone to empathize with his struggle.
