She’s painting the town red.

Meghan Markle stunned in a red-hot Carolina Herrera dress during her surprise appearance at the Children’s Hospital LA Gala on Saturday night.

The Duchess of Sussex posed on the green carpet at the charity event — which honors the Children’s Hospital LA’s patients and hospital pediatric workers — in the gown from the Pre-Fall 2022 collection, which she repurposed into a red U-neck bustier column dress.

Markle, 43, paired the look with red strappy heels and she wore her dark tresses in loose waves down her back.

Inside the gala, the mom of two smiled as she greeted nurses from the hospital and took selfies with them.

She was also photographed speaking to some of the young patients at the event, including Ella Nelson, who was diagnosed with stage 4 neuroblastoma when she was only 2 years old.

Other guests at the CHLA gala included Jimmy Kimmel, Kaley Cuoco, Al Yankovic, Jamie Lee Curtis, Colin Hanks, Molly McNearney and Demi Lovato, who performed at the event.

Makle’s husband, Prince Harry, was not present.

However, at the time, the gown had an A-line style train that extended from the hip to the floor and she paired the ensemble with matching Giuseppe Zanotti pumps.

Markle also wore her husband’s late mom Princess Diana’s Cartier diamond tennis bracelet.

The “Suits” alum walked the red carpet with the Duke of Sussex, 40, who presented the 2021 Intrepid Valor Awards to five US service members at the gala.
