Raise a glass to Willow Sage Hart‘s new chapter. 

The 14-year-old daughter of Pink and husband of 19 years Carey Hart looked more grown than ever in a photo of her first day of high school. 

In the pic shared to Instagram Sept. 4, Willow—rocking a cropped salmon-colored button-up shirt and a pair of blue jeans with a white belt—smiled for the camera while balancing a backpack on her shoulder and two thermos in her hands. To top of her more mature appearance, the teenager wore her short hair in a ’70s-style side part. 

And Willow wasn’t the only Hart family member embarking on a new chapter this fall. In a second slide, Carey shared a snap of his and Pink’s 8-year-old son Jameson Moon Hart keeping it casual in a white shirt, multi-colored shorts and orange sneakers for his first day of back in the classroom.  

“1st day of school for the kiddo’s!!!!” he captioned the heart-melting images. “So crazy that Willz is starting high school today.”
