"Teen Mom" is about to return with a new season, titled "Teen Mom OG," and the cast is not happy when the series' most infamous individual, sex-tape star Farrah Abraham, reenters the picture.

The upcoming season will premiere at 9 p.m. EST on March 23.

According to MTV:

In the juicy trailer below, we're immediately re-introduced to Amber's relationship with her ex Gary - and she has quite the colorful and expletive-filled statement about Leah's father having another baby. But the Indiana native, who is relishing her freedom, has a new love interest of her own and he's ready to commit. But is the 24-year-old ready to do the same?

Meanwhile, Maci's troubles with Bentley's father Ryan continue and she declares - through tears - that she won't allow her son to be ignored. That's not all: She and boyfriend Taylor are having a baby, and they adorably break the news to the production crew.

In addition, Catelynn and fiancé Tyler share the exciting moments following their positive pregnancy test - we even see them embracing after the stick flashes "yes +." But how do their families react to the bundle of joy on the way?

Finally, Farrah makes a belated entrance to the series - and her appearance is met with mixed reviews by her fellow cast members. How do they respond when they hear the decision to bring Farrah back into the fold? Well, their surprised expressions say it all...
