Congratulations are in order for Pink and her husband Carey Hart, who are getting ready to welcome their second child - and pretty soon, by the looks of it!
The 37-year-old singer shared the happy news via Instagram this weekend, posting a beautiful photo that shows off her very pregnant bump. Her simple caption - "Surprise!" - is a fitting one, seeing as she somehow managed to keep the baby on the way out of the headlines until now. (See the picture here!)
Pink's 5-year-old daughter Willow also joins her in the photo, sweetly cuddling up to her mom's growing belly.

The Grammy-winner has been outspoken about motherhood since she and Carey welcomed their daughter in 2011. She's been a fierce breastfeeding advocate, a force against post-baby body shaming and even a defender of the so-called "Terrible Twos." Just last year, Pink opened up about how being a mother has given her a new perspective:
?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,? she said. ?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."
Congratulations to Pink and family on the wonderful news!
