Secret Children, Rehab & Rape Claims: What To Expect On The New Season of 'Teen Mom OG'

Seven years after their TV debut on 16 & Pregnant, Maci Bookout, Farrah Abraham, Catelynn Lowell and Amber Portwood return to Teen Mom OG for their most jaw-dropping season on August 22— and RadarOnline.com has all the details.

Bookout, of course, just welcomed her third child, son Maverick Reed, with fiancé Taylor McKinney. And we'll likely see the Tennessee native planning for her October 7 wedding.

But her pregnancy was marked by scandal when fans claimed she drank while expecting. Though she ignored the claims, perhaps she'll finally address the shocking accusations on the show this summer.

As per usual, sex-tape star Abraham has continued to create controversy. She stripped down for a raunchy Easter-themed photo shoot, and lashed out at Rob Kardashian's fiancée Blac Chyna in a racist rant on social media. "F***in monkey," she wrote.

In a terrifying incident, Abraham told fans she was nearly raped by an Uber driver on a late-night ride from hell. (She said a boyfriend protected her from the attacker.)

Road to rock bottom: In another sad turn, Teen Mom OG fan-favorite Lowell, who suffered from post-partum depression after the January 2015 birth of daughter Nova, checked into rehab in March for anxiety and depression issues.  She checked out after one month.

Of course, Portwood's past few months have been the most stomach-churning of all the women. She lost primary custody of her daughter, Leah, and was ordered to pay ex Gary Shirley $1,200 a month in support. In other legal trouble, she was slapped with a federal tax lien for $130,000.

But the financial drama pales in comparison to her relationship problems. As RadarOnline.com exclusively revealed, Portwood's wayward fiancé, Matt Baier, owes thousands in child support for at least nine secret children. (He had initially only told his girlfriend about two children, later upping the total to five.)

How will Portwood react? RadarOnline.com also revealed that Baier's late ex-girlfriend accused him of sexual assault in a scathing restraining order filing.
