The original moms are back! The cast of MTV’s “Teen Mom OG” will return for a sixth installment of the hit docuseries in 2016. While fans wait to catch up with stars Farrah Abraham, Maci Bookout, Amber Portwood and Catelynn Lowell, MTV has released four sneak peeks of the upcoming season.  The clips will air as part of MTV’s “Behind the Cameras” special Monday at 10 p.m. EST.

Sneak Peek No. 1 — “Farrah Has No Time For Her Producers”

Farrah lashes out at “Teen Mom” co-executive producer Larry Musnik in the season’s trailer and in her sneak-peek video. 

In the footage, Farrah can be seen ignoring Larry’s request to give her a phone number. After he complains the network’s logo is being improperly used for one of her business ventures, Farrah tells him off. “Then I won’t be a part of the logo and then you guys can go eat s---,” she says.

Farrah attempts to leave the scene of their argument by driving off. When Larry refuses to close her car door, Farrah backs up her vehicle. The clip ends when a police officer approaches the pair and Farrah claims she does not work with Larry. The officer closes Farrah’s door and allows her to leave.

Sneak Peek No. 2 — Catelynn and Tyler Rehash An Old Wound”

Catelynn and Tyler Baltierra pay a visit to the diner – this time with their daughter Nova – where they once considered calling off their engagement. Tyler reveals he did not speak to Catelynn for two weeks after the incident, in which he discovered she had been unfaithful. Catelynn says the scene almost made her not sign on for “Teen Mom” Season 2. 

“I didn't want the world to see how f----d up I am,” Catelynn says.

Tyler says he thought it was important to show their faults.

Sneak Peek No. 3 — “A Competitive Amber Bonds With Her Producer”

Amber and her fiancé, Matt Baier, visit an indoor go-kart track to have some fun with the “Teen Mom” producers. Amber says the main thing that bonded her with her “Teen Mom” crew was the hard things she went through on camera. Producer Heather Walsh says she had no idea Amber was “on drugs” during the beginning of the show, but thought she was “crazy” due to her arguments with Leah's dad, Gary Shirley.

Sneak Peek No. 4 — “Never Before Seen Footage With Maci”

Maci sits down with her producer Kiki and says she feels like they're family. Despite considering the crew members of her brood, a later scene shows Maci having a disagreement with Kiki.

When Kiki reveals she is able to get ahold of Maci’s ex-fiancé, Ryan Edwards, to film, Maci says she doesn’t want to be involved with him.  “We don’t talk about him, see him, talk to him, nothing,” she complains of her son Bentley’s dad.

When Kiki says Maci’s family will be the focal point of her segments, not Ryan, Maci gives in.
