Sydney Sweeney’s Red Carpet Transformation Has Everyone Talking — Her New Haircut Changes Everything.NN

Sydney Sweeney debuted a major hair transformation at the AFI screening of her film “Christy” in Los Angeles Saturday.

The actress, 28, chopped off her long hair and also changed up the color.

She sported bright blond locks instead of the darker hue she was photographed with earlier this month at the “Christy” premiere at the London BFI Film Festival.

Sweeney’s hairstylist, Glen Coco Oropeza, shared the week-long process of transforming Sweeney’s hair in an Instagram post Saturday.

”Couldn’t be happier with this dreamy and glossy outcome,” he wrote.

Celeb hair colorist Jacob Schwartz also posted about working with Sweeney, calling her new hair color “bleached suede blond.”

Sweeney paired her newly shorn and dyed locks with a plunging pale pink halter gown by Miu Miu.

The “Euphoria” star’s beau, Scooter Braun, didn’t make an appearance with her Saturday though a source told Page Six that she’s previously asked the music mogul for career advice.

“She enjoys having someone to ask advice from about her career,” the source told us earlier this month.

We’re told Sweeney also “enjoys spending time” with Braun, 44. But our source cautioned, “Don’t expect any wedding bells… Her number one priority is her career.”

Sweeney has been getting Oscar buzz for “Christy” due to her portrayal of trailblazing female boxer Christy Martin.

She underwent a body transformation to play Martin, putting on 30 pounds of muscle and sporting a brown mullet for the film.

“I didn’t fit in any of my clothes,” she told W magazine about her weight gain. “I’m usually a size 23 in jeans, and I was wearing a size 27.”

“My boobs got bigger,” she added. “And my butt got huge. It was crazy! I was like, Oh my god.”
