Farrah Vs. Catelynn And Tyler, Round 5: Lowell Calls Former ‘Teen Mom’ Costar Abraham ‘Gross,’ Baltierra Makes Dig At Sex-Tape Star’s Bedroom Habits

This Teen Mom feud is far from over.

Farrah Abraham’s sworn enemy, her former MTV costar Catelynn Lowell, recently expressed her disgust at the 23-year-old porn star’s line of sex toys molded from her own anatomy.

“This is gross bet her parents r proud,” Lowell, 23, scoffed on July 20, retweeting a photo of the erotic novelist’s life-size Topco products.

Meanwhile, Lowell’s fiancé, Tyler Baltierra, 22, got involved in another of Abraham’s feuds: When Breaking Amish star Sabrina Burkholder joked about the “Blow” singer’s criticism toward Teen Mom 2 star Jenelle Evans’ second pregnancy, Baltierra couldn’t help but retweet Burkholder’s shocking comment.

“Um Farrah Abraham says she wouldnt have a kid again without a plan?? Yeah obviously.. you need to take it in the right hole first sweetie,” Burkholder tweeted on July 17, referring to Abraham’s infamous moves on her Backdoor Teen Mom sex video.

The former Teen Mom costars began throwing shade on June 9, when Abraham told Starcasm it makes her “very sad” to see the couple “make poor choices” by becoming pregnant five years after giving their first child, daughter Carly, up for adoption.

“Huh bad choices?!? Hahaha I didn’t make a so-called ‘sex tape’ but WE make the bad choices?” Lowell promptly fumed.

Not that she was ever a big fan of the Backdoor Teen Mom star: Lowell and her original Teen Mom cast members Maci Bookout and Amber Portwood reportedly refused to film an encore season of their former MTV hit if Abraham participated.

“Catelynn always thought Farrah was fake, right from the first season of Teen Mom,” the insider told RadarOnline.com in June. “She was always desperate for fame.”
