Mason Disick was having a ball as he hit up a Malibu, Calif., park yesterday.
Flanked by not only his mom Kourtney Kardashian, but also aunt Kim Kardashian, little Mason could't keep that grin off his face!
Even though they were just at the park, Kim was as stylish as ever in her chic blazer, as Kourtney showed off her fast-growing baby bump in a clingy grey dress.
Mason had a blast climbing across the monkey bars. This kid definitely has no fear of heights!
