It’s a boy! Maci Bookout welcomed her third child on Tuesday, May 31. The Teen Mom OG star and her fiancé, Taylor McKinney, named their baby boy — and second child together — Maverick Reed.

The MTV personality shared the happy news via Twitter: "Mr. Maverick Reed has officially made his debut & completed our family. So much love, so many blessings!"

Bookout, 24, already shares son Bentley, 7, with ex Ryan Edwards and daughter Jayde, 12 months, with McKinney, 27.

Prior to giving birth, the Tennessee native explained why she chose the unique name. “Maverick was actually one of our boy name choices when we were pregnant with Jayde before we knew it was a girl,” she revealed during an interview with MTV News. “Reed is a family name for both our families.”

The happy couple also considered the name Connor, but ultimately decided that Maverick “went better with the names Bentley and Jayde.”

Earlier this year, the reality star revealed to Us Weekly that she found out about the pregnancy in January, just two days after McKinney proposed.

“I was at the doctor, ironically, to get my birth control prescription refilled!” she said, initially joking that the doctor had the “wrong results” and “mixed them up.”

Bookout and McKinney — who plan to tie the knot in October — previously stated that they are “absolutely” not expanding their family of five.

“There are going to be some permanent birth control decisions made,” Bookout told Us in February.
