Farrah Abraham's on-again, off-again boyfriend, Simon Saran, took aim at the fiance of Amber Portwood earlier this week on SnapChat.

As the latest episode of Teen Mom OG aired on Monday night, Saran suggested, presumably without base, that Matthew Baier was a pedophile.

"He is the red dot in your community, watch out for him," Saran told fans, according to a report by Perez Hilton on Tuesday.

Saran then warned Portwood's 7-year-old daughter, Leah, to stay away from Baier, who is engaged to the reality star.

"I would be nervous too sweetheart, you don't want to sit on that man's lap," he advised.

Saran then said that Portwood's ex-fiance, Gary Shirley, the father of Leah, has "every right to be worried about his daughter."

In response to Saran's claims, Portwood took to Twitter, where she shot down the idea that her fiance was a pedophile.

"Simon your a little b***h who lets a girl talk mad s**t to you. Your weak and irrelevant. Your a little boy toy puppet," she wrote, continuing, "How is he a pedophile lol.. Where does that even come from? Stfu and be the little boy toy weak a** person you are."

No word on any response from Saran in the days since Portwood's tweets were shared.
