Jennifer Lopez has already done a Fiat 500 commercial, but that was more like a JLo music video and Fiat’s role was not that remarkable. In this new ad the Fiat is heavily featured. It is about going back to your roots, or something. We are more interested in why they chose Jennifer Lopez as Fiat 500’s ambassador. Granted, 500’s a girly car. But is that because they both have big but rather nice back-ends?!

Watch ‘My World’ commercial after the jump.
