Songstress P!nk has opened up about being a mother to her first child, daughter Willow Sage, and explained that she's constantly excited about the future now that she has a family.

During an interview with Billboard magazine, the 'Who Knew' superstar explained that Willow has 'changed' her life in ways she couldn't have imagined:

"It's nuts. She's so much fun. She has made everyone very happy this year -- the whole crew. She just changed everything. I didn't used to think about ever stopping."

"And now I'm like, 'I can't wait to find her school. What's she going to be like when she's eight?'"

P!nk added that she hopes to have another baby in the future and wouldn't say no to adoption:

"My brother is everything to me. So I want her to have family beyond her Papa and me. For that reason, I mostly want another one for her to have a lifelong friend... I want to adopt, I want to have more -- just, yes."
