Mackenzie McKee has left her husband.
This is a development that comes as not much of a surprise to anyone who has been watching Teen Mom OG.
The couple got married in August of 2013 and share three children -- Gannon, 7, Jamie, 5, and Broncs, 3 -- but they've been experiencing some difficult times for awhile.
Specifically, Josh has had to answer questions about his fidelity, as depicted on this season premiere of Teen Mom OG.
"I would like to say, that due to stress, me needing to stay focused, the media, etc. I am deciding my marriage needs a break," Mackenzie tweeted on Friday, Aug. 16, adding in this message:
"My heart breaks for my kids. But as of right now, this is what’s best. Thank you."
Mckee also took Instagram to share a selfie alongside the caption
"Freshly single and ready to, be the boss babe that I am and let God lead me to what I deserve."
McKee rose to quasi fame on Teen Mom 3 and then re-joined this MTV franchise just a few weeks ago.
On the August 5th opener of this series, McKee opened up about how her husband was often on the road due to his job as a rodeo guy and that she suspected he was being unfaithful.
Mackenzie actually received a text from a woman on this episode who alleged that her husband went out to a bar and cheated on her -- and Josh was with him at the time.
This wasn't the only allegation of infidelity against Josh, either.
In an exclusive interview with OK Magazine, a woman claimed that Josh was caught with a mystery blonde at the Thirsty Armadillo located at The Stockyards in Fort Worth on Saturday, April 27.
"My friend and I saw Josh McKee and another guy walk in the bar," this insider told the tabloid, adding:
"They walked over and joined a group of about 5 or 6 girls. Within a matter of minutes he started talking with a girl with long blonde hair. They started making out and kept on kissing. Like couldn’t keep their hands off each other. They left the bar together hand in hand."
“My entire world just changed,” Mackenzie vaguely wrote on social media shortly before this story came out.
“You guys seemed solid,” one person wrote to Mackenzie after she confirmed the separation.
“We were,” Mackenzie replied. “We were truly best friends. It’s all just devastating.”
When pressed by other followers on Tweeted who learned she was leaving Josh, McKee added:
“I know in my heart he loves me. This was my decision."
As noted above, news of the split comes after this month's episode of Teen Mom OG that featured Mackenzie worrying about her husband possibly cheating on her after he went out of town for a rodeo.
What did Josh say after this allegation came out?
"There was no affection or anything like that there," he said on the show, continuing:
"I'm just here to tell you that I was at a bar, and I'd like you to trust me when I'm getting a few drinks at a bar... I was just avoiding the fight, and I was wrong."
McKee has effectively replaced Bristol Palin as a Teen Mom OG cast member this season.
She's already brought more drama in just a few weeks than Bristol did over a full year on the series.
