Remember Pink?  The R&B singer-who-once-worked-with-LA-Reid-turned-rocker? She recently gave birth to a little girl, on Thursday in Los Angeles. The pop star took to Twitter to tell the world about baby Willow Sage Hart.

“We are ecstatic to welcome our new beautiful healthy happy baby girl, Willow Sage Hart," Pink wrote. "She's gorgeous, just like her daddy [Carey Hart]. #beyondblessed”

Pink first confirmed she was pregnant in November after she was spotted sporting a baby bump and received a congratulatory Tweet from a pal on the social networking site.
"I didn't want to talk about it because I was just really nervous and I have had a miscarriage before," the singer explained to Ellen DeGeneres on her talk show.
Since the confirmation, the edgy pop star has openly gushed about impending parenthood.
"I have a life inside of me, and I want her or him to know that I will accept him or her with open and loving and welcoming arms,” she wrote on her Web site to accompany the release of her video for her single, "F-----' Perfect." "And though I will prepare this little munchkin for a sometimes cruel world, I will also equip this kid to see all the beauty in it as well."
