“Teen Mom OG” star Catelynn Lowell has arguably had one of her toughest seasons on the hit MTV reality show, and things aren’t any easier on social media. After one of her Snapchat videos were taken down for “inappropriate content,” Lowell lashed out Friday.

She called the person who reported her “r-------,” which is an offensive term against mentally disabled people. The controversy was over Lowell sharing a video of daughter, Nova, playing in the shower. Since some of her private parts showed, some people accused the MTV star of sharing “child porn.” Others were concerned that Nova was potentially exposed to “perverts.”

“Wow is all I can say,” she wrote at first, later deleting the offensive post.

After she used the R-word, Lowell quickly issued an apology Friday. “Sorry I used the R word. And if I offended anyone never once did I mean that,” she said. “I am truly sorry. I also have family [member] that has special needs.” Her mea culpa wasn’t greeted with an outpouring of sympathy, attracting less than 500 likes from her 1.25 million followers.

Tyler Baltierra, Lowell’s husband, seemingly defended her. “Engaging with someone unworthy of a reaction only gives the opponent the power,” he said Monday. “If you keep the power on your side, they have no ammo.” The tweet garnered more than 1,400 likes from his 908,000 followers.

“Teen Mom 2” star Jenelle Evans reportedly got involved in the spat, slamming Lowell for her use of the derogatory term.

“Cate, to be honest that was very low and I’m actually shocked you said that,” Evans wrote on Twitter in a post that was later deleted, according to Radar Online. “Please think before tweeting again.”

The cast just filled a reunion special that is packed with drama. An air date for the reunion has yet to be revealed by MTV.
