Maci Bookout's Baby Bump Gets Some Love From A Very Special Someone

The 'Teen Mom OG' cast member just posted the cutest picture EVER.

Even though Maci Bookout has some time before she welcomes her third child, the "Teen Mom OG" cast member's munchkin is already getting some sweet attention from an adoring family member.

"Baby Jayde showing her little brother some love before bed," the 24-year-old -- who shared her exciting news on Valentine's Day and is due on May 30 -- captioned the heartwarming photograph above, showing the infant laying on her mama's bump. "My heart is so full," she added. Completely valid emotional status, Maci!

Even though JC is a bit too young to understand that she will (soon!) be a big sister, the little lady looks very content bonding with her parent and her sibling-on-the-way. And speaking of the bun in the oven, Maci spoke with MTV News about her second son and how she's feeling during this pregnancy.

"Because it’s the third one, you know what’s going on," the "Bulletproof" author revealed. "You’ve been there, done that a couple times now, so it’s sort of laid back."

To hear more from Maci about cravings and how her family reacted when she told them that she would soon welcome a brand-new addition, watch the video below. And be sure to catch Maci and her clan this Monday during the two-hour "Teen Mom OG" finale at 10/9c!
