TEEN mom fans are shocked after Farrah Abraham followed her ex-costar.
She appeared to get friendly with an old nemesis years after blocking the entire cast.
Farrah, 31, is now following Catelynn Lowell, also 30, on Instagram.
The two notoriously did not get along and feuded for many years when they starred together on MTV.
Farrah was one of the main women on Teen Mom OG with Catelynn before she got let go in October 2017.
Meanwhile Catelynn is still part of the franchise.

I CATE YOU!
Prior to her being fired due to her involvement in the adult entertainment industry, Farrah and the other OG girls – Cate, Amber Portwood and Maci Bookout – didn’t get along either.
In 2018, Catelynn slammed Farrah online as a “scared sissy” and told her to “grow a pair” after the star dropped out of a celebrity boxing match against Nicole “Hoopz” Alexander.
In 2020, Farrah shared a video of her daughter, Sophia, now 13, watching a video about learning how to pay taxes in the fifth grade.
The clip shaded Catelynn and her husband Tyler Baltierra, 30, because they at the time owed $800,000 in federal tax liens.

However, both Farrah and Catelynn have moved on a lot since their early MTV days.
No longer part of the franchise, Farrah likes to keep her followers on social media entertained with racy pictures shared on Instagram.
Earlier this year, she attended a trauma treatment center for a month after she was arrested outside a Hollywood nightclub.
Meanwhile, Catelynn is still with her husband Tyler.
They share daughters Novalee, seven, Vaeda, three, and Carly Davis, 13, who they gave up for adoption during the first season of 16 & Pregnant.

In 2017, they purchased a historic four-bedroom farmhouse which they have since made their home.
But the 150-year-old home is far from old-fashioned as Tyler, who flips properties, has renovated much of the house’s exterior and interior.
