Maci Bookout has finally revealed the first official photo of baby Maverick.
The 25-year-old Teen Mom OG star took to Instagram on Tuesday, posting an adorable close-up snap of her 3-month old son, whom she shares with fiancé Taylor McKinney.
"Hi World. My name is Maverick, and I'm the cutest little guy in the world!" she captioned the pic, which showed the tot wearing a "Team Dad" onesie. "Nice to finally meet you. #MrMaverick #HereIam @tmon3yyy."
The Tennessee native -- who is also mother to son Bentley, 7, and daughter Jayde, 15 months -- followed it up with a pic of all three of her kids dressed head-to-toe in orange and white in support of her favorite collegiate football team.
"The cutest Tennessee Volunteer fans I ever did see!" she gushed. "#GoBigOrange #VFL #VolNation @tmon3yyy #missjaydecarter #mrmaverick #bennybaby."
Over Labor Day weekend, Bookout shared snaps from her fun-filled bachelorette party in Las Vegas, Nevada. Ahead of her October wedding to McKinney, the reality star and her closest pals hit up the Liquid Pool Lounge at the Aria Resort, showing off their toned tummies in bikinis, which they styled with trucker hats emblazoned with "Bride" and "Team Bride."
