Pink is pregnant!

The Grammy-winning singer, 37, took to social media on Saturday to share that she is expecting her second child with husband Carey Hart.

“Surprise!” Pink wrote alongside a photo with the couple’s 5-year-old daughter, Willow Sage. The mother-daughter duo wore coordinating off-white ensembles and brown hats, and Willow’s head rested on her mom’s growing baby bump.

The musician and her motocross-champ husband welcomed Willow in June 2011.

“I have lived a lot of life in a very short time, and you get hardened a little bit — you get jaded, you build up walls. And when you see this little kid, and you get to watch them through infancy to toddler to little person, it’s amazing,” the singer previously told PEOPLE about motherhood.

“You see how you were. When you watch this bundle full of love and light that’s untarnished and untainted by heartache and any of the numerous things that change you, it’s very healing. It’s a miracle.”

Earlier this year, Pink opened up to Good Morning America about the possibility of adding to her family.

“I love being a mama. I made a choice a long time ago that I was going to have a successful family and that is my absolute No. 1 goal in life,” she said.
