Important development in Teen Mom 2 star Jenelle Evans's pregnancy, guys! In case you need a quick crash course in Jenelle's ovaries, this infamous Southern belle is pregnant with the fruit of her boyfriend Nathan Griffith's looms, and they're expecting their bundle of joy sometime in Summer 2014. Aside from some morning sickness and a few restless nights, Jenelle's pregnancy has gone off without a hitch, and we're happy to report that the baby is doing well.

Jenelle is so excited about the bun in her oven that she treated her fans to an exclusive video of her sonogram, in which you can hear her baby's heartbeat! In said video (which was captioned "The baby is healthy, growing, and doing PERFECT!"), Jenelle's nurse can be heard telling her that he heartbeat sounds great (135/140). Phew! And for those naysayers who still think girlfriend is faking it, that is most definitely her stomach being probed. We'd recognize those signature tattoos anywhere.

Jenelle may not have been prepared for motherhood the first time 'round, but this girl is far from being sixteen and pregnant. Nowadays, she's a full-fledged adult with her own house, a successful job and a great boyfriend! Sure, Jenelle still doesn't have custody of her son, Jace, but she's well on her way to permanently reuniting with her little man. Life is finally looking up!

Are you surprised that Jenelle got pregnant even though she doesn't have full custody of Jace? Weigh in below.
