Pink is going to be a mum again! On Saturday, the singer confirmed the exciting news on Instagram by posting a precious snap of herself showing off her growing baby bump next to daughter Willow. Along with the snap, Pink wrote, "Surprise!" Husband Carey Hart then posted the same photo moments later and captioned it, "😳😳😳😳😳🍼🍼." Pink and Carey tied the knot back in January 2006, and are already parents to 5-year-old daughter Willow. Congrats to the couple on their growing family!
