Work it girl!

Pink stepped out in a sexy biker-chic ensemble that was fitting for her weekend of motorcycle riding in Malibu with her baby daddy, Carey Hart.

The So What singer Tweeted over the weekend: "Motorcycle rides, and i can feel summer waning. Beautiful day". Pink and her family moved to a larger home in Malibu this past January in anticipation of baby Willow’s birth, and the refreshing sea air seems to agree with the pop star.

The new mama appears to have slimmed-down before our very eyes, and her above outfit definitely highlights her thin post-baby bod!
