‘Mad Man’ takes first wife

JON Hamm wed his “Mad Men” co-star Anna Osceola (below) Saturday at Anderson Canyon in Big Sur, Calif. — where they first met while filming the show’s mind-blowing series finale.

Hamm, 52, and Osceola, 35, beamed while saying “I do” at a star-studded ceremony overlooking the sea at sunset.

The bride wore a strapless white gown with a plunging neckline, plus a thigh-high slit revealing strappy white heels.

She went for minimal jewelry and makeup, with only a dainty necklace and a bracelet. The former Don Draper looked dapper in a classic black tux.

Fans of the show may recognize that the location was famously used in the final “Mad Men” episode, when Hamm’s advertising exec whiz character transcendentally came up with the iconic “Hilltop” Coca-Cola ad.

Guests included show co-star silver fox John Slattery, who was seen snapping pics of the groom on his cellphone before Osceola walked down the aisle to “You Only Live Twice” from the 1967 James Bond film.

Other A-listers at the wedding included Paul Rudd, Larry David, Tina Fey, Brooke Shields and fellow newlywed Billy Crudup.

After the ceremony, Osceola changed into a midnight blue gown.

Their engagement was first reported in February, though sources told Us Weekly it “happened a while back.”

The bride and groom are very private and neither uses social media.

Hamm and Osceola met on the set of “Mad Men” in 2014, but they were not romantically linked until 2020. He was previously in a longterm relationship — from 1997 to 2015 — with writer and actress Jennifer Westfeldt.

Hamm told Howard Stern of Osceola last year that the relationship had “opened up the possibility of things like being married, having kids, you know, defining a new version of happiness, life, wellness.”
