On her twitter page pink wrote, "We are ecstatic to welcome our new beautiful healthy happy baby girl, Willow Sage Hart. She's gorgeous, just like her daddy. #beyondblessed."During the week, the 31-year old singer hinted on twitter that she had given birth, but would not confirm or deny it until recently. Pink mentioned that ""New Moon in Gemini today :) a good time to start something new...." Her cryptic message led many to speculate on a possible birth, but she only confirmed the birth in her latest tweet. Congrats to both Pink and Carey on their new family.
