Pink surprised fans on Saturday after posting a snap of herself and her daughter, five-year-old Willow, revealing a large baby bump.
The Just Give Me a Reason singer, who is cradling her bump with one hand and has her other arm around her daughter while dressed in a flowing summer dress, has kept her pregnancy under wraps until now, and captioned the sweet snap with a simple "surprise!"

Fans were quick to congratulate the 37-year-old on the exciting news, with one writing: "Congratulations! You look so peaceful and serene!"
"You are a beautiful pregnant woman and Willow is so… sweet! So happy for you!" another added.
The baby will be Pink and her husband Carey Hart's second child together. The singer and Carey Carey wed in 2006 with some ups and downs in their relationship along the way before welcoming their daughter and soon-to-be big sister Willow in June 2011.
The proud mother hinted that she wanted more children in an interview with Good Morning America back in May.
"I love being a mama," she revealed. "I made a choice a long time ago that I was going to have a successful family and that is my absolute number one goal in life."

Previously speaking about motherhood to People magazine, the star said: "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.
"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."
