Maci Bookout's cutie pie son Bentley is gearing up to be an older sibling to his baby sis on the way, and the "Teen Mom OG" cast member shared a darling glimpse of the six-year-old already showering his mama's mini-me with some love. Prepare to outfit Benny in a "best big brother" T-shirt as soon as this petite princess makes her triumphant arrival.
Maci -- who will welcome Baby Jayde Carter in June with beau Taylor McKinney -- added the heartwarming Instagram snapshot below of her son and longtime boyfriend giving her burgeoning, purple-clad bump a couple of kisses. Better watch out, puppy Bonnie -- everyone wants to cuddle up to M's tummy!
"Jayde and I are the luckiest girls in the world thanks to these two wonderful men!" the 23-year-old wrote along with the aww-worthy image from a recent maternity photo shoot which features M's doting guys holding -- and sweetly smooching -- her eight-month belly. Only a short matter of time until they're actually cradling the precious peanut and B is besties with his younger relative.
The Tennessean also posted a loving pic with T, and there's no denying this couple is really ready to meet their little one. It's the final countdown...
Be sure to catch M on the season finale of "TMOG" on Monday at 10/9c -- and for a fun rewind, watch B learn that his "mother is having another" in the clip below!
