Kristin Cavallari has cut off her hair.

The 27-year-old former "The Hills" star  took to Instagram Thursday to share a photo of her new look under the caption: "Short hair don't care."

Cavallari credited famed celebrity stylist -- and 'The Rachel' creator -- Chris McMillan for her new look.

A few hours before sharing a photo of the final product, the former "Laguna Beach" star posted an image of her long blonde locks tied into a pony tail and chopped.

"This is happening right now," Cavallari wrote along with the photo. "Just chopped off my hair!"
