Kourtney Kardashian is once again a mom-to-be, but despite being months along in her pregnancy, she is still spending plenty of quality time with her two-year-old son Mason Disick.

The hot mama took Mason to the Kidnasium in San Diego, California on Tuesday afternoon for a day of fun. Kardashian announced her pregnancy at the end of November, although she was only a couple of months along at the time, and more recently revealed she will be giving birth to a baby girl!

While spending the day with Mason, Kourtney kept it casual and tried to cover her baby bump in flowing orange top and tight jeans, trading in her signature high heels for a pair of black flats. Mason, meanwhile, kept it stylish himself in a checkered, multicolored sweater and moccasins -- he takes just after his dad, huh?!

Scott Disick, the father of Mason and Kourtney's longtime partner, was nowhere to be seen during the family outing, so Kourtney and Mason really did get to spend some quality time alone together -- too cute!
