'Teen Mom' Stars and Their Kids

The Baltierras say someone in production "should have had the decency to call us."

The stars of "Teen Mom OG" learned Bristol Palin would be joining the cast of their show the same time everybody else did, once it hit the news.

And that, in their minds, isn't cool.

Catelynn and Tyler Baltierra were guests on Kailyn Lowry and Lindsie Chrisley's Coffee Convos podcast this week, where talk inevitably turned to failed VP candidate Sarah Palin's daughter appearing on the next season.

When asked how they felt about Bristol joining the cast, neither of them took issue with Palin herself, just how MTV handled everything.

"Do I have anything against her as a person? No. Do I dislike her? No, 'cause I don't know her," said Catelynn. "Do I think it's weird that you're throwing somebody into the original girls' story? Yes."

Lowry, who went through something similar with Brianna DeJesus joining "Teen Mom 2," could empathize. "It's like nobody gets a call," she said. "Like, we're making a huge change to the show. This is what's happening. It hits the media before we found out."

"It's the only problem I have with it, is the way that it came out in the media and stuff," Tyler added. "It's like, we start the franchise, built it, sustained it for 10 years, I think we deserve the respect to let me know what's going on when you're doing a major franchise shift that we helped build, create, sustain. So I feel like it's more of a respect thing."

Catelynn agreed, saying the higher-ups "should have had the decency to call us."

"Hey network, you like your money? You're welcome," added Tyler. "Give me the respect and let me know when you're doing a major franchise shift."

When Lindsie suggested the decision to keep them in the dark was to keep Brisol's casting a secret as long as possible, the Baltierras said they can be trusted.

"We worked with them for 10 years and nothing's ever leaked out," said Catelynn. "You should be able to trust us." She added that, in her mind, even a heads up the day they were going to make the announcement would have been nice.
