In 2008, returns to the music scene with her fifth major studio album "". The effort lines up Al Clay, Billy Mann, Butch Walker, Danja, Greg Wells, and Max Martin as her team on the production table. The first single off the record is entitled "So What" and shares the story of the singer's separation from motocross racer, Carey Hart, whom she married in early 2006. "I think it's really ironic that it's this kind of subject matter, and it's my first No. 1," Pink says.
Since released on August 15, "So What" has reached number one on numerous charts in several countries, including Australia, Canada, German, and Ireland as well as U.K. and U.S. Beside helping her scooping the charts' reigns, "So What" also helps her working out a healthy friendship with her ex-husband. "It's helped both of us, because we had to figure out how we could have a really, really healthy friendship. The fact we can still laugh together and piss each other off, roll our eyes at each other, throw our hands up in the air and at the end of the day it's good - we're solid," she explains in a further statement.
