Jared Leto sent hearts racing when he took to Instagram on Sept. 15 and put his bulging biceps on display in a mirror selfie. Showing off his incredibly toned physique, the 48-year-old Oscar winner cut the sleeves off a white T-shirt by Enfants Riches Déprimés which further revealed his rippling muscles. “Starting the Tron workout …join me?” the Suicide Squad actor captioned the photo.
