We've got some exciting news for you, Teen Mom 2 fans! After much speculation, we can now confirm that our girls Jenelle Evans, Leah Messer, Kailyn Lowry, and Chelsea Houska are returning to their rightful place on our small screens. According to our friends at MTV, the show's highly-anticipated fifth season will premiere on Tuesday, January 21 at 10 p.m. ET. In other words, mark your calendars!

It would be an understatement to say a lot has happened since Season 4. Where do we even begin?!

In the trailer below, we see newly-pregnant Jenelle cuddling up the beach with boyfriend Nathan Griffith, which means poor Courtland Rogers (you know, Jenelle's estranged husband who's currently chillin' behind bars at the Brunswick County Jail) has been left on MTV's cutting room floor. Ouch! Of course, that also means we'll likely skip over Jenelle's dark times, aka when she got hooked on hard drugs and was arrested for heroin possession and paraphernalia, which we're thinking is probably for the best.

As for Leah, the West Virginia mountain mama is unfortunately still struggling with daughter Aliannah's mysterious medical condition while trying to effectively co-parent with ex-hubby Corey Simms. Oh, and apparently hubby Jeremy Calvert almost filed for divorce at one point. Wait, what?!

Meanwhile, newlyweds Kailyn and Javi have just learned that they're expecting their first kiddo together (spoiler alert: he's adorable!), but the stress of planning their second wedding is really starting to put a damper on the celebration. And then there's Kail's baby daddy Jo Rivera, aka Nerd in a Cool Kid's Body (you didn't think we forgot about that, did you?), who will stop at nothing to take her down in court over custody of baby Isaac.

And last but not least Chelsea finds out that her baby daddy Adam "Chintee" Lind and his new girlfriend Taylor Halbur have their own bundle of joy on the way. Oh, and he also wants to take her to court. But the good news? Little Aubree is pretty much the cutest and most stylish kid on the face of the planet and we can't wait to see her strut her stuff all season long.

You got all that?! Check out the epic, drama-filled trailer for Teen Mom 2 Season 5 below, and don't forget to tune in on Tuesday, January 21 at 10 p.m. ET on MTV!
