They're back! MTV released the trailer for the 2016 season of “Teen Mom OG” on Monday, revealing that like previous installments of the long-running docuseries, Season 6 will also be a dramatic ride.

In the trailer the four original teen moms return, Amber Portwood, Maci Bookout and Catelynn Lowell each giving viewers a look into their lives, but it’s controversial lead Farrah Abraham whose cameo is the most noteworthy. During the final few seconds of the teaser, Farrah can be seen in a yelling match with the series’ executive producer.

“I don’t need to be a part of a trashy a-- show anymore,” Farrah tells the EP, seemingly revealing the show will, once again, break the fourth wall. Farrah goes on to claim that she “makes millions” from other business ventures outside of the reality program. “I make millions of dollars doing other s---,” she says. “What a dumb, twisted motherf-----.”

While Farrah’s exact net worth isn’t clear, she is successful outside of the “Teen Mom” franchise. The former sex tape star most recently hawked the monthly subscription service BooksBoks on Twitter, using her daughter Sophia’s help, and the Pranamat msassage mat. As International Business Times previously reported, Farrah is also a New York Times best-selling author with four books under her belt, three of which include romance novels.

Elsewhere in the trailer, Catelynn, Maci and Amber appear to be battling problems of their own. After welcoming daughter Jayde, Maci is seen telling her boyfriend Taylor McKinney she wants him to commit to their relationship. “I want to be his wife. Make me your wife,” she says.

Meanwhile Catelynn, who is finally walking down the aisle to her middle school sweetheart Tyler Baltierra, is seen having pre-wedding jitters. In one scene Tyler’s mom suggests her future daughter-in-law might be suffering from post-partum depression. She and Tyler welcomed daughter Nova on New Year's Day. 

Like Farrah, Amber’s storylines doesn’t appear to be drama-free. She is seen discussing her impending custody battle with ex-boyfriend Gary Shirley over their daughter Leah. In one scene, she tells Gary to discuss their personal matters when the MTV cameras are not present.
