Pink, real name Alecia Beth Moore, and her husband Carey Hart are celebrating the birth of their first baby.
Pink, 31, tweeted yesterday: "We are ecstatic to welcome our new beautiful healthy happy baby girl, Willow Sage Hart.
"She's gorgeous, just like her daddy."
The singer met Hart, 35, in 2001 at the X-Games and following a brief separation in 2003, Pink proposed to her motocross beau in June 2005.
The couple married in January 2006 and then separated in February 2008 however after marriage counselling and working through their issues, Pink confirmed in February 2011 that she and Hart were back together and expecting their first child.
In November, Pink told Access Hollywood about the unusual name she and Hart were considering at the time. "My dad's name is James, and my brother's name is Jason...Carey's middle name is Jason, [and] Jameson - we like whiskey. That's a no brainer."
In November, she released her Greatest Hits...So Far! album, which included a new song dedicated to her unborn child.
She wrote on her blog the significance behind the track, ‘F***ing Perfect’: "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.
“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."
