The baby news was confirmed Saturday by publicist Meghan Kehoe after Pink posted a baby-bump shot with 5-year-old daughter Willow on Instagram. The caption read simply, “Surprise!” There were no further details. Complementing her motherhood, the 37-year-old singer is a children’s advocate through UNICEF. Last year, she was named an ambassador to help promote physical activity in young children in the United States.

Pink also raises money through UNICEF for nutritional relief for malnourished children worldwide, and she’s the national spokeswoman for the UNICEF Kid Power fitness band.
