Catelynn Lowell had some good moments and some bad ones on this past weekend’s episode of Teen Mom OG. The good was her gender reveal, when she and Tyler Baltierra learned what most had suspected all along–that they were having a baby girl.

You’ll recall that Catelynn Lowell and her boyfriend gave up their first baby girl–Carly–for adoption, deciding at the time that they simply weren’t mature enough to raise a child. The two have weathered many storms since then, are now engaged, and expecting their second chance at parenthood–at least on the show.

In reality, Catelynn Lowell and Tyler Baltierra have already welcomed their new bundle of joy.

Even though Farrah Abraham has yet to appear on an episode of Teen Mom OG (so far the show has featured Catelynn Lowell, Amber Portwood, and Maci Bookout), she has managed to get in some hurtful digs from backstage. Probably the most insulting remark she made was aimed at Catelynn Lowell.

The jab took place as Catelynn Lowell was speaking with the show’s host about ending her ongoing feud with Abraham. That’s when the former porn star dug her nails in deep.

“There’s somebody still in denial,” she said to the show’s producers, snickering 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.

“She just burned bridges with everybody. What an idiot,” Amber Portwood said as she, Catelynn Lowell, and Maci Bookout simply shook their heads in disbelief at what they were hearing Farrah Abraham say.

Fortunately for Catelynn, she knows what Farrah is all about. It would likely have stung far worse had Maci or Amber made a rude comment about her.

This is no doubt a clear indication of what future episodes of Teen Mom OG will entail–and they’re likely to get even worse when Farrah Abraham starts appearing in them.
