Sarah Jessica Parker Is Chic in Green Gown at Kensington Palace Party with Matthew Broderick

The 'And Just Like That' actress and her husband married in 1997

Sarah Jessica Parker and Matthew Broderick are a seriously stylish couple!

The pair attended the ATG summer party at Kensington Palace gardens in London, Wednesday, and Parker, 58, opted for a floor-length emerald green Elie Saab gown that featured a thigh-high split and cape-style sleeves.

She teamed her dress with a sparkling bag and a pair of green heels from her own SJP by Sarah Jessica Parker collection. Broderick, meanwhile, contrasted his wife perfectly in a smart gray plaid suit, blue shirt, and tie.

The evening was held in honor of the couple — who share son James Wilkie, 20, and twin daughters Tabitha Hodge and Marion Loretta Elwell, 13 — by the Ambassador Theatre Group and their CEO Mark Cornell.

"It was a total thrill to attend this eve's Summer Party at Kensington Palace Gardens thrown by our dear friends at the Ambassador Theatre Group," the actress wrote in an Instagram caption on Wednesday that accompanied a photograph of her in her look for the night.

"Matthew and I were truly touched to be honored, and delighted to play a part in raising money to support Sir Sam Mendes' Theatre Artists Fund. Thank you for having us," Parker added.

"We look forward to officially returning to London in just a few short months," she continued, before sharing details of her and Broderick's upcoming West End show, Plaza Suite, and how to pre-order tickets.

"See you there?" she wrote, signing off with her signature "X, SJ​."

Parker will be making her West End theater debut in the new show, which will begin its run at the Savoy Theatre in January 2024, while her costar in the show, Broderick, previously appeared in the famed London theater district in a performance of The Starry Messenger in 2019.
