'Hi, World': Maci Bookout Unveils First Official Photo Of Baby Maverick

And yes, the 'Teen Mom OG' tot looks just like his older bro Bentley

Maci Bookout has shared some sweet glimpses of her third child Maverick since his May arrival -- an introduction video right after he was born and the infant bonding with dad Taylor McKinney, to name two instances. Now, the Tennessean is offering an official look at her second son -- adorable close-up and all. Say hello to Bentley's twin!

"Hi World. My name is Maverick, and I'm the cutest little guy in the world! Nice to finally meet you! #MrMaverick #HereIAm," Maci -- who is currently chronicling her third pregnancy with Maverick on this season of Teen Mom OG -- captioned the photograph above of her handsome nugget, who is staring straight ahead at the camera with an extremely cute expression.

And because one image of Baby M wasn't enough, Maci shared a collage-style snap of her three kiddos -- all showing off their team spirit for their mama's favorite football team.

"The cutest Tennessee Volunteer fans I ever did see! #GoBigOrange #VFL #VolNation @tmon3yyy #missjaydecarter #mrmaverick #bennybaby," she added. Delicious cheerleaders, if we do say so ourselves.

Be sure to keep watching Maci and her clan every Monday on Teen Mom OG at 9/8c -- and check out a sneak peek from this week's upcoming episode below.
