Rock star P!nk gave fans good reason to "Raise Your Glass," announcing the birth of her new baby girl Thursday evening.

"We are ecstatic to welcome our new beautiful healthy happy baby girl, Willow Sage Hart," P!nk tweeted. "She's gorgeous, just like her daddy."

This is the singer's first child with her husband, motocross racer Carey Hart.

Hart later retweeted his wife's message with one tweak, insisting, "[Willow is] gorgeous, just like her mamma!"
