MTV appears to be pulling the plug on “Teen Mom 2.”

The controversial documentary series, which follows the adult lives of four women who became pregnant in high school, is shutting down production, multiple sources tell The Post.

The decision to end the show follows several months of erratic, headline-grabbing behavior by loose-cannon star Jenelle Evans.

Since Thanksgiving, Evans has become pregnant again, got married, lost her baby and publicly demanded a divorce.

“You f – – king leave out of town and I might be having a miscarriage?! F – – k U, U f – – king piece of sh – t,” she tweeted to her husband, Courtland Rogers, last week.

Evans, 21, also shared what appeared to be disturbing, play-by-play updates of her seven-week pregnancy ending.

“And this is the end, I think,” she shared with 632,800 followers Friday. “Feel light headed.”

Hours later, Evans tweeted that she was with her ex-fiance, Gary Head, at a North Carolina bar.

Insiders say producers are concerned the attention-seeking reality star has become a liability for the show, which tries to characterize itself as a cautionary tale about the hardships of too-young motherhood.

MTV, once unafraid to push the limits of taste and exploitation, appears to be more protective of the image its programs project than in the past.

Last week, Oxygen abruptly scrapped “All My Babies’ Mamas” — which documented the relationships between rapper Shawty Lo and the 10 mothers of his 11 children — after charges the show projected a negative stereotype.

“Teen Mom” producers, still reeling from bad press over cast member Amber Portwood, who was jailed last year on drug charges, have been unable to tone down Evans’ out-of-control antics.

Since first appearing on MTV, Evans has been arrested seven times on charges including breaking and entering, assault, violation of probation and possession of drugs.

The scandal-plagued star has publicly feuded with her family and other cast members, been forced to give up custody of her 3-year-old son and posed for nude photos which were later leaked on the Internet.

In 2012, Evans was committed to rehab for a second time by her mother, amid tabloid reports of heroin addiction.

“Jenelle is nothing but bad publicity for MTV,” says Ashley Majeski, editor of TheAshleysRealityRoundup.com.

“She feeds off the public and the recognition of the fans, and I don’t see why they would want to have anything to do with that.”

Still, “Teen Mom 2” has remained a ratings bonanza for the former music channel, pulling in more than 3.4 million viewers for its Season 3 premiere last November.

The spinoff of “16 and Pregnant” features newlywed Kailyn Lowry, South Dakota mom Chelsea Houska and recently remarried Leah Messer-Calvert, who is expecting her third child next month.

Some cast members are still awaiting official notice of the cancellation, a source says.

A network rep declined comment.

A fourth and final season of “Teen Mom 2” has already been filmed, and is expected to air sometime this year.

The original “Teen Mom” series concluded its run in October.
