Pop star P!nk has become a first-time mom after giving birth to a baby girl.

The So What hit-maker sent gossips into a spin on Wednesday by posting a cryptic message on Twitter.com hinting she'd delivered her baby.

She posted, "New Moon in Gemini today... a good time to start something new.... Also called the Honey Moon."

And Pink has now confirmed she and husband Carey Hart are the proud parents to a little girl, named Willow Sage Hart.

In a post on her Twitter.com page on Thursday night, she writes, "We are ecstatic to welcome our new beautiful healthy happy baby girl, Willow Sage Hart. She's gorgeous, just like her daddy. Beyond blessed."
