Pop singer Pink and motocross racer husband Carey Hart welcomed Willow Sage Hart into the world on Thursday.

We are ecstatic to welcome our new beautiful healthy happy baby girl, Willow Sage Hart, the singer, 31, tweeted. She's gorgeous, just like her daddy.

Pink met Hart, 35, at the X-Games in 2001. They got married in 2006 but in February 2008 the couple separated. After Pink's career resugence with So What, a break-up anthem written about Hart, the couple attended marriage counseling and announced in February 2010 that they were back together. Pink announced her pregnancy last November.

Let's a take a look back on Pink's most memorable fashion moments and hope thart baby Willow will be just as fashionably experimental as her mother.
