"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 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 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.

"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.

Farrah Abraham didn't mince words when it came to dolling out blame for Valerie Fairman's death ... and "16 and Pregnant" fell right in Farrah's crosshairs.

Farrah -- a former "16 and Pregnant" star herself -- was at Headquarter's Gentleman's Club in NYC where our photog asks her pointblank if the show and the fame played a role in Valerie's death.

Check out the vid ... Farrah says the show is now toxic.

As we reported ... Valerie died Wednesday from an apparent overdose.

First responders rushed to Valerie Fairman initially thinking she might have suffered a heart attack ... but once on scene there were signs of possible drug abuse.

TMZ got the dispatch call to the fire dept and EMS Wednesday night in Coatesville, PA ... and the call went out as a "cardiac arrest" -- but about 10 minutes later the dispatcher changes the call to a "possible DOA."

Valerie Fairman was desperately trying to get clean for years before she died from a suspected overdose ... according to her mother.

Valerie's mom, Janice Fairman, tells TMZ her daughter checked into 5 different rehab treatment facilities over the last 5 years, but she fell off the wagon every time. She says the last time was just a few months ago ... after Valerie had served time in prison for a probation violation.

Janice tells us she last spoke with Valerie a week and a half ago, and while they didn't discuss her sobriety, Janice says Valerie sounded "way up" and "very good."

As we reported ... Valerie died Wednesday while visiting a friend Pennsylvania. Janice says she does not know the friend.

Valerie Fairman -- the 23-year-old star from the reality show "16 and Pregnant" -- has died and her family tells TMZ it appears to be an overdose.

Valerie's mom tells us she was at a friend's home in Coatesville, Pennsylvania Wednesday when the friend repeatedly called for Valerie, who was in the bathroom, but she did not come out. We're told the friend broke down the door and found her unresponsive.

The coroner is conducting toxicology tests to determine the exact cause of death but we're told it appears to be an OD.

Valerie's child, 7-year-old Nevaeh, is currently with her mom.

As for Valerie, she has been arrested a number of times. The charges include prostitution and, just last week she was busted for resisting arrest and providing false ID to law enforcement. She attempted to run from cops, who subdued her.

RIP

Jordan Cashmyer has checked into rehab after her drinking spiraled so out of control, she gave herself a concussion and a black eye ... TMZ has learned.

Sources close to the "16 & Pregnant" star tell us Jordan's spending 30 days at a rehab facility in Baltimore. Her rock bottom started earlier this month -- we're told Jordan's booze habit started affecting her job at a gym ... and she got fired.

Then late last week, after a night of heavy drinking ... she stumbled into her mother's house and fell so hard, she smacked her head on the ground and suffered a concussion.

Our sources say the injury made Jordan realize it's time to "get her life together."

"16 and Pregnant" star Lindsey Harrison just had a huge victory in court -- she's been awarded all parental rights to her 5-year-old daughter.

Lindsey, who's 21 now, got a managing conservatorship over her daughter, Aniyah Monroe Harrison-Ponce.

According to legal docs ... Aniyah's birth father, Forrest Dean Ponce, has been absent for 6 months, and failed to support his daughter for at least a year.

"16 and Pregnant" star Whitney Purvis says her adorable Boston Terrier Chumpy ran away and was adopted by a new family before she even had a chance to look for him, so she's fighting the rescue shelter to get the pooch back.

Purvis says Chumpy was being watched by neighbors while she was on vacation when he ran away.

Animal control says they picked up a Boston Terrier Sept. 23 and kept him for the 3-day stray hold. No one claimed him, so the dog went to Boston Terrier Rescue of East Tennessee and someone adopted him.

Whitney says BTRET refused to ante up the name of Chumpy's new fam.

BTRET claims they did everything by the book, adding the dog wasn't tagged or microchipped.

Here's where the story doesn't add up ... animal control says it picked the dog up Sept. 23, the day before Whitney left for her trip ... so someone's lying.

We get all the fuss ... Chumpy's a cutie!

Former "16 and Pregnant" mom Whitney Purvis tried to clean up -- allegedly attacking her ex with a broom -- and still got herself arrested. Again.

Purvis was busted in Rome, GA on Wednesday afternoon after police say she broke into Weston Gosa's home by throwing a wheel through 2 windows -- and then whacked Gosa with a metal broom handle.

She allegedly hit Gosa in the leg and side. 23-year-old Purvis was booked for felony aggravated assault and misdemeanor trespassing.

Purvis and Gosa are familiar with jail -- they've been arrested multiple times for everything from DUIs to stealing a pregnancy test.

Weston Gosa -- the dude who knocked up Whitney Purvis on "16 & Pregnant" -- was arrested again Tuesday ... and his mug shot is the absolute best of the trilogy.

Law enforcement sources tell us ... Weston was pulled over in Georgia for speeding and driving on a suspended license. He's currently being held at the Floyd County Jail in Rome, GA on a $1,710 bond.

As we previously reported -- Weston was busted last December for smashing some electronics ... and popped again last July after allegedly crashing his car while driving under the influence (which spawned the infamous "sleeping mug shot").

Are the people who cast that show that good ... or just lucky?

Whitney Purvis and her boyfriend/baby daddy Weston Gosa -- stars of MTV's "16 & Pregnant" -- were arrested in Georgia this week after allegedly smashing the hell out of some electronics ... TMZ has learned.

The Floyd County Sheriff's Dept. tells us ... 21-year-old Whitney and 23-year-old Weston were arrested on December 12th ... after someone filed a complaint accusing the two of smashing a laptop and a cell phone.

We're told a warrant was issued for their arrests ... so cops went to their home and arrested the reality stars for criminal trespassing.

Both Whitney and Weston were taken to the station where they were booked. They were each released on $1,300 bond.

After a year-long crash course on good parenting skills, "16 & Pregnant" stars Ebony and Joshua Rendon were finally granted full custody of their three-year-old daughter again, TMZ has learned.

TMZ broke the story ... The Department of Human Services stripped the MTV stars of custody of their daughter Jocelyn last year, after police found deplorable living conditions in their home like feces covered walls, maggots and flies.

But all that's behind them now. TMZ spoke to Josh, who says he and Ebony enrolled in a rigorous program of counseling and parenting classes to learn how to care for their child and were officially granted full custody again.

Josh says, "Our family is finally back together and we are doing great. We got the help we needed and did what we needed to do. We will never make the same mistakes again.”

Josh tells us, there are no restrictions placed on the custody agreement, but over the last year they were subjected to random home inspections by the DHS.
