"Teen Mom 3" star Mackenzie McKee may have wrecked more than her car recently. Her bull rider husband, Josh McKee, threw her wedding ring in the toilet and walked out over the weekend, reports TMZ.

The "Teen Mom 3" couple has reportedly been arguing since MacKenzie drove their new, uninsured Kia Sorento into a ditch in March. Josh was hog hunting with friends when the accident happened. For unclear reasons, Mackenzie was driving the Sorento to search for him. According to TMZ, 310 Shakes, a meal replacement program that Mackenzie features in many social media posts, paid the $10k bill for the repairs. It didn't stop their marriage from imploding, especially when Mackenzie first blamed her diabetes for the car accident, but then said it happened because of her "rotten husband."

During a "TMZ Live" interview in March, Mackenzie said the crash happened because she was out searching for his "no good huntin' hog a**."

Sources told TMZ their two year marriage has been on the rocks. The couple reportedly had a huge argument over the weekend that ended with Josh throwing her wedding ring in the toilet before he walking out.

The reality TV couple's relationship has been unstable from the start.

Hollywood Life reports that Josh began dating Mackenzie on Feb. 24, 2010. She got pregnant and they welcomed a son, Gannon McKee, on Sept. 12, 2011. They were engaged to be married but called off their engagement October 2012. They got engaged a second time in January 2013 and married Aug. 17, 2013.

Three months after the marriage, Dr. Drew interviewed Mackenzie on the "Teen Mom 3" reunion episode where she admitted that she and Josh were cheating on each other.

Another relationship issue revealed during the interview was that Josh had suffered head trauma while bull riding and got hung up on painkillers. His whole personality changed, Mackenzie said, before he quit the painkillers. He had agreed to give up bull riding at that time and attend school for criminal justice.

But that didn't happen, as evident by a picture posted to Mackenzie's Instagram on April 17, along with a caption that mentioned her and Gannon accompanying Josh on a rodeo gig.

The couple has a son, Gannon McKee, 3, and daughter, Jaxie, 1.
