They’re baaack! Maci Bookout, Amber Portwood, Farrah Abraham, and Catelynn Lowell — the original stars of MTV’s successful series Sixteen & Pregnant and Teen Mom — are back for the network’s upcoming series Teen Mom OG, and it’s safe to say it’s going to be three against one as the girls are not happy about Abraham’s return.

In a dramatic first-look at the season, Bookout continues to have drama with her ex Ryan and reveals she’s expecting again with her boyfriend Taylor. Meanwhile, Portwood, who was released from prison in November 2013, continues to fight with her ex Gary while navigating a potential proposal from a new beau. And fan-favorite couple Lowell and Tyler Baltierra, who welcomed newborn daughter Nova Reign last month, reveal the moment they announced they’re going to be parents again after placing their first-born daughter Carly for adoption.

On top of managing their own respective issues, the girls are also faced with a big surprise — the return of Abraham. When Bookout finds out from the crew that the erotic novelist is going to be returning, she threatens: “You guys can leave now. This is over.”

Her confrontation with the crew is just the beginning of what viewers will see behind the scenes, though.

“In a first for the Teen Mom franchise, Teen Mom OG will break the fourth wall, pulling back the curtain to reveal their relationships with the producers and crew, the challenges of raising children on camera, and how life in the public eye has shaped them as parents and people,” MTV revealed in a press release. “Each episode will give an unprecedented look into these young mothers’ lives and how they’re facing the responsibilities of parenthood as their children enter kindergarten, start little league, and reach other milestones of youth.” 

Watch the trailer above! Teen Mom OG premieres on MTV Monday, March 23, at 10 p.m.
