Betty Cooper, is that you? Lili Reinhart shared photos of her natural curly hair over the weekend—serving the best Olivia Newton-John as Sandy in Grease realness. The Riverdale actress took to Instagram Story on December 29th to share selfies of her blonde wavy locks, writing, “Let the curly vacation hair begin” and adding, “my natural frizz and curl thank you very much.”

Before we get to the photos, let’s take a moment to observe what Reinhart’s hair usually looks like.

Reinhart’s waves are a major departure from the straight ponytail she rocks as Betty Cooper on the CW series Riverdale. In an interview with PopSugar back in July, Reinhart discussed the tolls heat styling for her character’s look has taken on her hair.

We’re glad Reinhart’s hair is on a natural-hair vacay this holiday season. We personally think it looks FAB, girl.
