Matthew McConaughey jeans sunglasses nike track jacket j. k. livin

Just because it's December, don't expect Matthew McConaughey to give his cardio routine a break!

We spotted the 42-year-old actor leaving the gym yesterday, and while he wasn't frolicking around on the beach without his shirt on, he still looked pretty handsome! Matty sported one of his j.k. livin beanies, and we have to say, it's good to see a celeb actually promoting their own company.
