Amber Portwood's fiance, Matthew Baier, has reportedly been caught ranting about her fellow MTV star Kailyn Lowry, of Teen Mom 2.

In a series of uncovered tweets from months ago, Baier dissed Lowry's looks.

“Kailyn’s face breaks my TV,” Baier wrote in one tweet, according to a report by Radar Online on Tuesday. “The worst thing that ever happened to high definition is Kailyn’s face #DAMN”

In another, he used Lowry's co-star to insult her, telling fans, “[Jenelle Evans] is a good mom like Kailyn is good looking.”

The longtime Teen Mom viewer, who began dating Portwood in 2014, also said the cameras must add “110 pounds,” because Lowry’s head is “the size of the Snoopy ballon at the Macys parade.”

He then took aim at Lowry's book, and said, “What was the topic of Kailyns book? How to bang ugly dudes, cheat in a shower and have my face always look like I’m allergic to shellfish?”

While Baier was clearly not a fan of Lowry or Evans, he took a liking to Farrah Abarham, and even suggested they go out.

“I think they should do a teen mom beauty pageant. Although [Farrah Abraham] would win in a landslide #TeenMom,” he wrote.

On Twitter, Portwood is staying silent about the issue, leading many to wonder if they've split, but so far, that doesn't appear to be the case.
