A representative for FIAT confirmed to Jalopnik that Jennifer Lopez wasn't in the Bronx for a commercial about her being from the Bronx. The reason? In this "increasingly mobile" world, J. Lo is just too busy for the block, so they shot her wherever she was.
Here's the full statement:
Both FIAT commercials featuring Jennifer Lopez were indeed filmed in the Bronx as well as outside locations. In today's world, people are increasingly mobile and their work takes them to a variety of locations. As a result, we took the opportunity to film wherever Ms. Lopez was working at the time to accommodate her schedule.
Much like the original ad that created this controversy, you'll miss the reality if you don't pay closer attention. The car was there, but Lopez was not.
