The celeb shares the news on Twitter, saying...
"We are ecstatic to welcome our new beautiful healthy happy baby girl, Willow Sage Hart. She's gorgeous, just like her daddy. #beyondblessed"
This is the first child for Pink and hubby Carey Hart.
She announced her pregnancy on Ellen back in November, saying, "I didn't want to talk about it because I was just really nervous and I have had a miscarriage before, but if I was going to talk about it with anyone, it was going to be with you."
Congratulations to the new parents!
