Maci Bookout Is Pregnant With Baby Number 3 & She's Already Flaunting An Adorable Bump — PHOTO

Exciting news for all you Teen Mom fanatics out there (because I know I'm not the only one addicted to this franchise): Maci Bookout is pregnant with Baby No. 3! The 24-year-old MTV star announced the exciting news in a fitting Valentine's Day Instagram post that showed off her baby bump and revealed that she and fiancé Taylor McKinney are expecting a baby boy (a little brother for Bentley, 7, and Jayde, who will turn one this May).

"#makingmoremoneys," Bookout captioned the sweet photo of McKinney (nickname: T-Money) cradling her stomach. "Baby boy coming soon! happy valentine's day! @tmon3yyy #lastbutnotleast."

In fact, there's a very good chance that Baby Boy McKinney and Miss Jayde Carter may actually be less than a year apart. Because, as Bookout told MTV, she's due on May 30 — just one day after Jayde's first birthday. If she gives birth earlier than her due date, even just by two days, girlfriend will have two kids who were born within a year of each other. Talk about timing!

And speaking of timing, Bookout told MTV that she learned she was expecting right after McKinney popped the question.

"I found out I was pregnant with baby number three right after we got engaged," Maci explained. "It was not expected or a planned pregnancy."

As any Teen Mom sleuth would know, the timeline there is a little off. Bookout and McKinney announced their engagement — and made it seem like they got engaged — just three weeks ago, on Jan. 19. If Bookout is due on May 30, that would mean she is approximately 5 and a half months along, meaning that she either knew she was pregnant before they got engaged (not likely, considering she said she didn't find out until afterwards) or that they secretly got engaged months before they actually announced the engagement (which makes the most sense — it fits with Bookout's version of the story, and it's no coincidence that McKinney would do a Teen Mom Facebook Q&A two days after their engagement announcement, unless it was all pre-planned). Sneaky, sneaky, Maci and Taylor!

While Bookout made the pregnancy announcement in her happy-go-lucky way, leave it to the good-natured McKinney to share the news with this hilarious meme:

Congratulations, Maci and Taylor!
