Pink's daughter Willow has dyed her hair purple for 7th birthday

The singer allows her children as much free reign to express themselves as possible, and it's evident in her daughter's new hair style.

During Pink's Beautiful Trauma show in Los Angeles on May 31, her 7-year-old daughter Willow Sage made an appearance on stage with her.

The sweet little girl wore a wavy patterned top, a pair of black leggings with a pastel-colored insert, and a pair of purple headphones. What surprised people most was the matching purple hair.

Pink proudly carried her daughter about the stage after her rendition of Raise Your Glass.

The singer's husband Carey Hart also took to Instagram to share a photo of their daughter.

"Have you met my daughter Wednesday Addams??? Love you munchkin. #MyDaughterIsMorePunkThanYours," Hart captioned the image of a serious-looking Willow.

Hart also shared another photo of Willow, this time with her younger brother, 17-month-old Jameson Moon. The sweet little children appeared to be playing in the sand on a beach, while an adorable bulldog pup climbed over the little boy.

Pink told People in a previous interview that she tries her best to create a gender-neutral environment for her children at home.

“I feel like gender-neutral is in itself a label and I’m label-less. I don’t like labels at all so I believe that a woman and a girl can do anything,” she said. “I believe that a boy can do anything. So I have boys that flip dirt bikes and I have boy friends that wear dresses. It’s all okay to me. It’s whatever floats your boat. So that’s the kind of house that we live in.”
