Kourtney Kardashian is All Smiles Amidst Scott Disick's Miami Fling

Kourtney Kardashian makes her way out of her car as she arrives at an art studio on Tuesday (January 31) in Calabasas, Calif.

The 37-year-old tv personality was all smiles as she stepped out with her kids – Mason, 7, Penelope, 4, and Reign, 2 – (not pictured) to drop Mason off at his weekly art class.

Earlier that same day, pictures of Kourtney‘s ex Scott Disick cuddling up with several models by the pool in Miami were released.

According to an inside source, Kourtney seems to be completely unfazed by the situation and doesn’t care what Scott does anymore.

FYI: Kourtney is wearing Vans shoes.
