Leonardo DiCaprio seems to be taking extra precautions when it comes to his health

The 42-year-old actor was spotted out with friends in New York City on Saturday, and had a noticeable object placed on his chest, under his gray T-shirt. A source tells gossip news that DiCaprio was in fact wearing a heart monitor for a "routine checkup," and is doing just fine.

On Friday, the Oscar winner was also photographed in Brooklyn while touring the garages for the inaugural Formula E New York City ePrix. DiCaprio did not appear to be wearing the medical device during this trip, though he was sporting a loose-fitting black collared shirt. During his visit, DiCaprio met with Formula E CEO Alejandro Agag and learned about the racing circuit, the way the cars are built and how the races are organized.
