Last weekend, Catelynn Lowell and Tyler Baltierra married in front of the duo's Teen Mom co-stars Maci Bookout, Amber Portwood and Kailyn Lowry.
The fourth T.M.O.G., Farrah Abraham, was persona non grata, however.
Why wasn't the Backdoor Teen Mom invited to the couple's nuptials?
Despite feuding for years, Catelynn and Farrah ended their beef on Couples Therapy last summer, so many were surprised she wasn't in attendance.
Don't be. There may not be as much vitriol, but there's still tension.
“Farrah has a tendency to make everything about her,” a source close to the couple said. “If she had shown up, she would have created a spectacle.”
Catelynn and Tyler have genuinely forgiven Farrah for her cruel remarks about them over the years, sources say, but they haven’t forgotten them.
“Farrah has made her feelings known,” the insider said.
“She had said a lot of terrible things about them.”
Most recently, at the Teen Mom: OG reunion taping, Farrah watched Catelynn from backstage talk to an after show host about ending their feud.
“There’s somebody still in denial,” Farrah said to producers.
“Still in denial in the land of white trash!”
Word got back to Catelynn, and while it wasn't shown on air and no Twitter beef erupted, it's safe to say this left a bad taste in Lowell's mouth.
