Teen Mom

The "Teen Mom OG" hole created by Farrah Abraham's firing is being filled by another 'TM' alum, Mackenzie McKee ... TMZ has learned.

Sources close to the production tell us the "Teen Mom 3" star, and fan fave, has officially joined the 'OG' cast, and she's already shooting scenes. As we told you, Farrah was 86'd and claimed, on her way out the door, MTV execs shamed her for doing porn.

We're told 'TM' producers recently pitched Mackenzie the idea of joining 'OG.' They were already shooting a 2-hour special with her about her mom's cancer battle. She was diagnosed earlier this year with stage 4 brain cancer.

We're told Mackenzie agreed to step in for Farrah and she's been filming for more than a week now.

You'll recall ... Mackenzie was part of the 'TM3' franchise before getting canceled after one season in 2013. She was very popular then, and fans have wanted to see her come back.

While Farrah's off fighting Viacom and MTV in court ... it looks like 'Teen Mom'-sters are getting exactly what they wanted.

"Teen Mom 2" star Adam Lind's still got some growing up to do ... because he's a wanted man for all the wrong reasons.

The Minnehaha County Sheriff's Department in South Dakota tells TMZ ... there's an active warrant for Adam's arrest for allegedly failing to pay child support. The warrant was issued on Valentine's Day.

We checked with the state office that handles these matters and we're told Adam was in the hole after 2 separate judgments were handed down last September -- one for $12,365 and another for $8,757.

It's unclear which kids this is about. Adam has 2 kids (Aubree, 8, and Paislee, 4) with 2 baby mamas ... including "Teen Mom 2" star Chelsea Houska, who is now married to Cole DeBoer.

Farrah Abraham's under the impression she's making some kind of humanitarian effort with her lawsuit against MTV's parent company, Viacom ... or so it seems.

We got Farrah leaving Craig's in WeHo Thursday night and talked to her about MTV kicking her to the curb shortly after she met with one of its honchos ... whom she says was hostile and threatening.

She says every celebrity has a sex tape, so getting the boot for hers is grossly unfair. She adds Viacom should be worried ... very worried.

Farrah Abraham says she's been bullied and ganged up on by MTV ... and the main reason she's suing is because she doesn't want her daughter to ever be treated that way.

Farrah was in L.A. Wednesday with her daughter, Sophia -- and a couple cute pups -- and she got into the lawsuit she filed against Viacom, MTV's parent company. She says it's no shocker she's going after them, after she was booted from 'Teen Mom.'

She insists she's on to better things now, but had to take a stand with MTV to set an example for her little girl. Sophia even voiced some support for her mom.

Farrah Abraham says a 'Teen Mom' honcho ridiculed her for her adult film work, and she's not gonna take it laying down ... she's taking the whole company to court.

Farrah says she met with Morgan J. Freeman (no relation), an executive producer on "Teen Mom OG," at her home in Texas last October. In a lawsuit, she says Freeman harassed, humiliated and degraded her doing porn.

The 'Backdoor Teen Mom' star says Freeman went on to threaten her future career at MTV, and she "feared for her life" because he was hostile toward her. According to docs, obtained by TMZ, shortly after the meeting MTV fired Farrah from the remainder of the 'OG' season, and also pulled the plug on negotiations for a long-term deal.

MTV aired portions of Farrah and Freeman meeting in a preview for the current season -- it was clearly tense, but there was no mention of her porn career in the clip that aired.

Farrah's suing Freeman, Viacom -- MTV's parent company -- and a few smaller production companies for at least $5 million.

"Teen Mom 2" cast member David Eason's officially been given the boot from the hit show ... TMZ has learned.

Jenelle Evans' husband came under fire for an anti-LGBTQ rant online Monday, and now MTV has severed ties. According to a network spokesperson ... Eason's comments do not reflect its views, and "with six weeks left of production ... effective immediately, we are ending our relationship with him."

Evans' co-star Kailyn Lowry told TMZ earlier Tuesday that she was disgusted and disappointed by Eason's comments ... and believed he should be kicked off the show.

In her husband's defense, Jenelle said she and David have gay friends and insisted he doesn't hate the LGBTQ community. She also apologized.

"Teen Mom 2" star Jenelle Evans is standing by her hubby, saying he doesn't hate members of the LGBTQ community ... and her evidence is essentially, "we know gay people."

David Eason came under fire on Twitter after he said, "Lmao why don't you go tell the homo and transgender parents to start teaching their kids better morals? Oh I forgot thats supposed to be normal." Both "Teen Mom 2" fans and cast members called for his firing from the show.

Now Jenelle's coming to David's defense, telling us, "David didn't understand how offensive people would get or how Twitter even works. Now that he realizes his voice is very strong within media/tabloids he has deactivated his account. He agrees he will keep his comments to himself from now on."

She continues, "David doesn't hate people from the LGBT community. My old manager was gay and used to be one of me and Davids close friends. We attended Farrah's birthday in Miami with a lot of LGBT people there and he didn't act in any type of way. We went had a good time and left."

Evans wraps her statement with, "We are sorry for the comments that were made."

11:16 AM PT -- David's page has been removed from Twitter.

Kailyn Lowry's disgusted by what her "Teen Mom 2" castmate said about gay and trans people, and wants him axed from the show ... TMZ has learned.

Kailyn's responding to Monday's online rant by Jenelle Evans' husband, David Eason, in which he said ... "Lmao why don't you go tell the homo and transgender parents to start teaching their kids better morals? Oh I forgot thats supposed to be normal."

He added he's not going to let his children associate with LGBTQ people or "be that way."

Kailyn tells us she's extremely disappointed in Eason, wants nothing to do with him and doesn't want her kids around him. She says she feels bad for his children for having to "grow up with someone that clearly holds so much hate towards others."

"Teen Mom" star Kieffer Delp may be back to his old ways of running afoul with the law ... cops arrested him for allegedly operating a meth lab.

Kieffer -- one of Jenelle Evans’ earliest boyfriends on the show -- was arrested after authorities in nearby Pittsburgh uncovered a suspected meth lab. Cops tell us they were called to an apartment building late Wednesday night and made the discovery.

Cops evacuated the building during the arrest because of a strong, lingering odor inside.

As we've reported ... Kieffer is a known drug user and he's previously been arrested for punching a girl and her male friend.

Most people demand bottles of Ciroc on their riders, but not Farrah Abraham, who's gonna be busy bedazzling her lady parts in her green room.

Farrah's hosting a XXXMas party at the Las Vegas stripper institution Crazy Horse III Thursday and her rider is about what you'd expect from a porn star ... neon panties and a vajazzle kit.

The former "Teen Mom" also gets very specific when it comes to hygiene, requesting "a pre-planned appointment with an affluent med-spa for service of 2 syringes of Sculpta facial filler," plus a 24k gold collagen breast firming gel mask.

The caring mom wants to care for the strippers ... demanding $3k in Crazy Horse III Diamond Dollars to tip performers.

Not much when it comes to food and beverage though, just one California sushi roll. It's how she ... rolls.

Farrah Abraham is losing deals all over the place ... first with work, and now with her real estate.

Farrah's finally gotten rid of her Austin home, but for a third less than her original asking price.

She listed the 4-bedroom, 4.5-bath in 2014 for $750k, only a year after purchasing it. No word on the exact selling price but it was in escrow for $520k.

The 3,300 square foot home has some history ... it was featured on the "Teen Mom" catch-up special "Being Farrah," but doesn't look like it helped move the sale. The stone slab work and the built-in BBQ in the backyard probably did though.

Farrah Abraham didn't go through with the anal she'd promised to do during her live CamSoda porn show Monday night and now the porn site is reimbursing everyone who watched.

It's unclear why Farrah bailed on the backdoor. Instead she didn't take off her lingerie, promoted her sex toy line and talked about her displeasure with MTV, who she says fired her earlier in the day for being an adult performer.

Either way, CamSoda wasn't happy and tells TMZ they were forced to go through with reimbursements since Farrah's porn show "created unfulfilled expectations."

The company also took a shot at MTV saying it was "reprehensible that she would lose her job because of a webcam performance." Farrah blasted MTV herself, saying it lost its biggest talent because of "women hating, sex shaming, hate crimes, selfish, Weinstein company power trip behavior..."

Farrah Abraham doesn't think Jenelle Evans should complain about "Teen Mom 2" edits that make her look bad -- 'cause that's not her job ... unless she wants it.

We got the OG "Teen Mom" star Thursday at LAX where we asked her to weigh in on Jenelle's gripes over MTV supposedly hyping her TV drama through edits ... and her threatening to walk away from the show if MTV doesn't do her right.

If there was ever a walking definition of "who gives a s***" ... it's gotta be Farrah. Besides ... the "Apply Now" button at MTV is always available, according to her.

Ditto for another 'Teen Mom' star, Kailyn Lowry, who's got her own take on Jenelle. In short, take a look at yourself in the mirror ... and your contract while you're at it.

Jenelle Evans is putting MTV on notice about the way she says it's portraying her and her fam on this season of "Teen Mom 2" ... saying she'll leave if they don't make it right.

We got Jenelle at LAX about a week after a huge blowup she and husband, David Eason, had on a season 8 episode. Fans blasted David for verbally abusing Jenelle, and also called her a neglectful mom.

Jenelle told us she's the victim of creative editing, done purely to create more drama, and she's pissed about it. She's also angry that producers are putting subtitles on her kid because it makes it seem like he has speech issues.

Long story short ... Jenelle says MTV is screwing itself, if it has dreams of bringing back arguably the most popular chick on the series.

Farrah Abraham's slightly used red gingham bikini and heels worn for the cover of "Girls and Corpses" can now be yours -- if you're into those things. Bikinis ... not corpses. Sicko.

The "Teen Mom" star did the photo shoot for the horror and comedy magazine's winter 2013 issue, and owner Robert Rhine is trying to make some cash off her wardrobe. He's listed the bikini and heels separately on eBay ... and says he expects to fetch thousands.

You can bid on Farrah's morbidly hot outfit until Sunday. If you're interested ... the top's medium, the bottom's extra small, and shoes ... size 9. And we know where your mind is right now.

Robert tells us he will donate all of the money from the sale to The American Red Cross to help victims of Hurricane Harvey and Irma.

According to the eBay post, all items were "only used for photo shoot and immediately put into a plastic bag."

"Teen Mom 3" star Briana DeJesus' baby daddy let a little thing like a weed citation snowball into a warrant for his arrest ... all 'cause he never showed up in court.

Law enforcement sources tell TMZ ... Devoin Austin was arrested Friday in Orange County, FL on an arrest warrant that was issued way back in August 2016.

The warrant stems from a traffic stop when cops cited Devoin for possession of weed and drug paraphernalia. He was supposed to be arraigned a month later, but never appeared -- hence, the warrant.

He could've gotten up to a year in jail or $1,000 fine for the original misdemeanor.
