She loves being the best mommy!

Kourtney Kardashian loves her kids so much, as evident by the amount of time she seems to spend with them (who wouldn't?). Case in point: the reality star escorted Mason and Penelope around Calabasas on Saturday. Aww!

The 35-year-old, who's expecting to add to the bunch with her third child with Scott Disick, has maintained her maternity style quite nicely as she keeps looking glam, baby bump and all.

Hold onto her Scott!
