Kailyn Lowry is all kinds of private when it comes to the bun in her easy-bake oven, but a new picture of her baby bump has finally surfaced on the interwebs, and girlfriend is huge!

Word on the streets is that Kailyn's about four months pregnant with her second child (she reportedly conceived while visiting her husband, Javi Marroquin, at his air force base over Valentine's Day), but check out home girl's belly. She looks well over four months along — especially considering that most mommies-to-be don't even start showing until around the fourth month!

The real conundrum? If Kailyn didn't get frisky with Javi over Valentine's Day, it means they conceived their little guy or gal in December, before Javi left Pennsylvania for Air Force boot camp in Texas. This would put Kailyn at a full six months pregnant, which means her baby could be due sometime in August!

Kailyn's been super cryptic about her due date, but one thing's for sure. She is not (we repeat, not) three months preggo.

"And no, I'm not 3 months along," Kailyn tweeted to a fan on June 14. "If you're gona act like a know it all get your facts straight."

Oh, and don't forget that this gal got a tattoo at the end of February, so it doesn't look like she found out about her pregnancy until sometime in March … the mystery continues!

How far along do you think Kailyn is, Teen Momers? Check out the adorable photo of her bump and tell us your theories!
