Farrah Abraham isn’t off to a good star with her Teen Mom OG costars. Following last week’s premiere of the show, she retweeted an unkind remark a fan made about Catelynn Lowell having given up her daughter for adoption five years ago. And on Sunday night’s episode she slammed Lowell again–referring to her as ‘white trash.’

Catelynn Lowell was speaking with the show’s host about ending her ongoing feud with Farrah Abraham. That’s when the former porn star dug her nails in even deeper.

“There’s somebody still in denial,” she said to the show’s producers, laughing over her remark. “Still in denial land of white trash!”

That wasn’t the end of her derogatory comments either. At least they weren’t all directed at Catelynn Lowell.

“From the past I never initially got along with the girls. They had some other issues with myself from the get-go…I would never confide in them,” Farrah Abraham said.

“Would I ever confide in people who are very fake and not real with themselves and kind of in denial and can’t empathize with someone? Of course not!” the erotic novelist continued.

Meanwhile Catelynn Lowell, Amber Portwood, and Maci Bookout could do nothing more than shake their heads backstage.

“She just burned bridges with everybody. What an idiot,” Amber Portwood said.

And yes, Farrah Abraham definitely burned bridges. Still the remarks she made about Catelynn Lowell were definitely the lowest of her comments. Catelynn did the right thing by giving her daughter Carly up for adoption–and she doesn’t deserve to be called trailer trash.

It will no doubt be a lengthy season on Teen Mom OG–both for Farrah Abraham, who seems hell bent on making life difficult for herself–and for those on the receiving end of her unkind barbs.

Hopefully Catelynn and the others didn’t take Farrah’s comments to heart. She is known for trying to build herself up by breaking others down.
