The former reality TV star is used to documenting her life on camera, as she was previously a regular on MTV's The Hills.
And although she is now focused on being a businesswoman and a mother, she still makes time to keep her followers updated on the goings on in her life.
Over the weekend, Kristin shared a few pictures of herself and her growing baby bump at home and it looks like she is already about to drop!
One of the sweet snaps shows the blonde star crouched on the floor and wearing a tight tank top that is clinging to her tummy.
She added the caption: "Baby bump getting BIG." You can say that again!
Playing in the background we can also spot Kristin's first child Camden, who was born in August 2012.
Another photo sees the ex-reality TV star keeping busy in the kitchen by making a wild mushroom and asparagus risotto. Nesting perhaps?
And even though her large bump is covered, we can still make out the shape underneath that cream top.
Kristin then posted one last snap of herself getting ready to go out on a date night with her husband Jay Cutler on Sunday (16 February).
This time, her stomach is hardly noticeable, as she is dressed up in an all-black ensemble.
Proving what a yummy mummy she is, Kristin has also styled her blonde locks into gorgeous waves and added a slick of pink to her lips.
She and her American football player hubby announced that they were expecting their second child in October.
And despite wanting to keep the sex of their unborn baby a secret, Kristin revealed this month that the couple are expecting another boy.
