Margaret Qualley is supported by fiancé Jack Antonoff at the NY premiere of Sanctuary

Margaret Qualley was joined by her fiancé Jack Antonoff at the New York City premiere of her upcoming film Sanctuary, held at Metrograph on Thursday.

The actress, 28, looked chic in a dress with a colorful floral top and simple black floor-length bottoms.

Qualley – the daughter of actress Andie MacDowell and actor Paul Qualley – completed her look with a pair of black heels.

Meanwhile, Antonoff, 39, was causally cool in a dark button-up, metallic blue pants and chunky black boots.

The outing came after the couple went on a double date with Taylor Swift and frontman Matty Healy from 1975 earlier today.

The Maid star swept her brunette locks into a bun for the occasion. She rocked delicate glamour, but opted for a vibrant red shade of lipstick.

The beauty kept her accessories to a minimum and wore simple gold earrings.

Meanwhile, the music producer rounded out his look with a hat and glasses with thick black rims.

Jack — who is best known for his work as a songwriter and producer on projects with Swift and Lana Del Rey — was rocking a white tote bag slung over his shoulder.

Lena Dunham’s ex-boyfriend – who also dated actress Scarlett Johansson in the past – stayed hydrated and carried two bottles of water in his hand.

Margaret and Jack were first linked in 2021 and went private about their romance before confirming their engagement in May 2022.

Earlier in the day, the pair were spotted with Taylor and her new British beau Matty on a double date at Casa Cipriani, as captured by a fan on social media.

An eyewitness told Page six that Swift and Healy sat next to each other in the celeb hot spot’s lounge, and that Swift and the rocker “cuddled and kissed” as they waited for their food.

At the event, Margaret also mingled with her handsome lead actor Christopher Abbott, 37, and director Zachary Wigon.

Abbott looked dashing in a linen navy blue suit and white T-shirt.

He completed his look with a pair of trendy suede orange boots and rocked a short beard.

Clare Noelle put on a sassy display on the red carpet, sporting a sultry black bustier and dark jeans with white stitching.

Executive producer Lisa Kjerulff looked chic in a white cami and black pants, which she paired with black slippers.

Élodie Ichter rocked an oversized plum top and black skirt and was joined by cinematographer Ludovica Isidori at the event.

Isidori put on a leggy display in a black mini dress.

Lachlan Watson, 22 – who uses she/she pronouns – rocked a form-fitting black dress with a black belt around their waist.

Actress Myha’la Herrold, 27, rocked a sheer black crochet dress and gray boots.

She was accompanied by Armando Rivera who looked dapper in a black suit.

Johnathan Fernandez, 38, showed off his style in a tan blazer, white T-shirt and slim-fitting jeans.

America’s Next Top Model star Jay Manuel, 50, followed the trends in an oversized blue blazer, white T-shirt, black shorts and matching black boots.

The cast and filmmakers were also seen posing together at the event.

Sanctuary follows a dominatrix named Rebecca and her wealthy client Hal, and the “disaster that ensues when Hal tries to end their relationship” according to IMDb.

Rebecca sees a way to exploit her wealthy client during a night in a hotel suite.

Hal is the son of a luxury hotel chain who is the heir to his father’s hotel and billion-dollar business.

When he is elevated to CEO of the company, he tries to end his deal with Rebecca, but she has other ideas.

In the film’s racy trailer, she sees an opportunity to cash in on his fortune, telling him he would never have gotten the job if she hadn’t made him the man he is today, and demands half of his new salary.

The dark thriller, which first premiered at the Toronto International Film Festival in September 2022, is scheduled for release on May 19.
