'Teen Mom 2' trailer: 'Mommy's going to have another baby!'
Leah Messer Calvert gets the most screen time, as the season will document some major life events for the 20-year-old: braces, divorce from the father of her twin daughters, Corey Simms, her subsequent engagement to Jeremy Calvert and their pregnancy. Although she suffers a miscarriage, Leah recently revealed she and Jeremy, now her husband, are pregnant again.
Jenelle Evans' tragic tale continues apace, dominated by drugs and jail. In one scene, Jenelle bawls, "I'm such a f*** up." (If she's talking about her Ed Hardy seat covers, afraid we have to agree.)
However, there is one new twist this season: a paternity test to determine whether deadbeat dad Andrew Lewis is really Jace's father.
Meanwhile, loafer Adam Lind gives baby mama Chelsea Houska a promise ring. When her dad, Randy, notices it, she says, "This is awkward" -- because Adam used Randy's allowance to buy it? (We kid!)
Some stuff happens with Kailyn Lowry, too, but nothing will ever be as interesting as that STD love triangle.
Season 3 of "Teen Mom 2" premieres Monday -- a new night -- Nov. 12 at 10 p.m. on MTV.
