By now you've all heard the fantastic news that Teen Mom 2's Jenelle Evans is expecting a baby with her MMA fighter boyfriend, Nathan Griffith — but you may not know when this bundle of joy is expected to make his or her entrance into the world or what Jenelle plans to name the little guy or gal. Lucky for you, Wetpaint Entertainment has all the exclusive details!

"The due date is June 29," Jenelle told us at Teen Mom 2's press day in New York City. "I'm 16 weeks yesterday."

As for the gender, the 22-year-old reality starlet plans to find out later this week, at which point she'll do a pregnancy gender photoshoot reveal — so keep your eyes on Twitter!

Either way, Jenelle's got her bases covered. She and Nathan picked out baby names as soon as they started trying to conceive (yes, people, this pregnancy was planned!).

"I let Nathan pick the guy's name which is Kaiser, but we haven't picked a middle name yet," Jenelle revealed. "And if it's a girl it's going to be Lydia Marie."

Kaiser and Lydia don't have a particular significance or meaning to Jenelle — she just really likes the way they sound. Kaiser, of course, is the German word for emperor while Lydia is a biblical name of Greek origin.
