Margaret Qualley managed a glamorous quick-change for her wedding reception with Jack Antonoff on Saturday night.

Jack, a music producer, and Margaret, an actress, tied the knot on Saturday in the picturesque seaside resort town of Beach Haven, New Jersey.

A dazzling array of famous faces lent their high-octane glamour to the proceedings, including Taylor Swift, who has worked on over 50 songs with the groom.

For the ceremony itself Margaret opted for simple elegance, draping her statuesque frame in a classic white bias-cut bridal gown.

She then speedily switched up her look for the afterparty, bundling into a still bride-appropriate white party dress with tulle half sleeves.

Playing up her screen siren features with flattering makeup including a slick of scarlet lipstick, she completed the look with a pair of ballet flats.

The bride and groom were seen after dark, joyously holding hands with one another as they dashed laughing out of the afterparty.

Jack enthusiastically led his new wife by the hand as she flashed her megawatt smile at her loved ones, waving at one of the guests while she followed her man.

Their celebrity guests were also still in attendance - in full force - as the nuptial afterparty on Long Beach Island stretched into the nighttime hours.

Several of the guests had brought their drinks outside into the fresh air, where Zoe Kravitz could be glimpsed giggling with Cara Delevingne and Taylor.

A gaggle of onlookers had duly formed, but they were successfully held at bay some distance from the wedding guests, who mingled under the glare of cellphone lights.

The fact that they were being watched, however, did not appear to put a damper on the proceedings, as the guests were seen laughing cheerfully with one another.

Jack and Margaret were first linked in August 2021, and were engaged less than a year later in May 2022, setting the stage for their star-studded wedding Saturday at Parker's Garage & Oyster Saloon in Beach Haven.

The wedding has proven to be a frenzy ever since guests started arriving, with Taylor fleeing the rehearsal dinner venue Friday night after hundreds of Swifties swarmed into the street outside.

So many fans flocked to Black Whale Bar & Fish House, just to catch a glimpse of their idol, that the street was shut down and the police arrived to prevent the tumult from spiraling out of control.

On Saturday Margaret, who was a scene-stealing presence as a member of the Manson Family in Once Upon A Time In Hollywood, welcomed a jaw-dropping variety of boldface names to her nuptials with Jack.

Along with her mother, Groundhog Day star Andie MacDowell, the attendees included names like Zoe Kravitz' boyfriend Channing Tatum.

Lana Del Rey, who like Taylor has a longstanding professional relationship with the groom, banished her summertime sadness with a sprightly pink-and-white look.

Jack, whose dating history includes Girls impresaria Lena Dunham, was classically stylish, going down the aisle in a black tuxedo and matching tie.
