You guys! Teen Mom 3's Mackenzie Douthit is like a giant inflatable balloon and she's totally about to pop! This professional cheerleader is currently eight months pregnant with her second child, and she's been photo-documenting each month of her pregnancy for fans.

Suffice it to say, girlfriend is enormous. Mackenzie's baby bump has doubled in size since her 7-month picture, and we can't even imagine how big she'll be once she reaches the 40-week mark. Of course, leave it up to this girl to not gain an ounce of weight anywhere except her belly. Mackenzie still looks fit and amazing, and we have no doubt that she'll be sporting a six pack within weeks after giving birth.

So is Mackenzie having a boy or a girl? Despite the fact that we're sure her hubby, Josh McKee, would love another son to ride bulls with, this happy couple are expecting a lil' lady! Mackenzie and Josh have been busy preparing for the new cowgirl in their life, and we anticipate her being swaddled in a pink camo blanket immediately upon popping out of Mackenzie. #blessed

What do you think of Mackenzie's 8-month baby bump? Can you believe how big she's getting?! Time to start taking bets on how much her baby will weigh…
