Kristen Stewart is back in black!

The actress has rocked platinum hair or dirty blond hair for the better part of 2016, but she's switched it up and gone dark.

Her hairstylist Adir Abergel shared an image of Kristen's new look on Instagram as she prepared to be a guest on "The Ellen DeGeneres Show."

"This happened in the middle of my day. Love my boo. ❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️ #kristenstewart #hairbyadir #ellen," he captioned the photo of the dark-haired actress.

Kristen throws up a peace sign and looks into the camera while wearing a black lace tank, white silk skirt and a silver lock necklace.

Kristen, of course, is naturally a brunette.

In October, Kristen was bleach blonde at the New York Film Festival screening of her latest film, "Certain Women." At the time, few paid attention to her hair, though, because she brought new arm candy with her, new girlfriend and alt rocker St. Vincent.

"They spent almost every day together after that," a source told Us Weekly of the romance.

Kristen and St. Vincent, who previously dated Cara Delevingne, were first seen together in late August at a comedy show in Los Angeles. On Oct. 4, they were spotted at lunch in New York and photographed the next day walking the streets of the Big Apple together. Us reports that Kristen also attended St. Vincent's concert in Los Angeles on Oct. 9.

"It's been very romantic," the source adds. "Kristen is always whispering closely in her ear and asking her opinion."

Kristen previously dated her "Twilight" co-star Robert Pattinson. Normally tight-lipped about her private life, she told Elle U.K. in September that she is more open with her personal life since she began dating women.

"I was like, 'Actually, to hide this provides the implication that I'm not down with it or I'm ashamed of it,' so I had to alter how I approached being in public," she said. "It opened my life up and I'm so much happier."

In Elle's November issue, she again spoke a bit about her love life and her decision to be a little more transparent.

"Things have changed," she said. "And not just with me — we're really allowed to encourage this new acceptance and be awesome."
