Neither Catelynn nor her husband Tyler Baltierra congratulated Radtke on his announcement. The relationship between the two siblings has appeared to be strained over the last few years, with Radtke posting a video on his Instagram in January alluding to a distance with his sister.

"You know it's bad when people on the internet feel more like siblings then [sic] your actual siblings," Radtke wrote over the video.

Catelynn and Tyler first appeared on 16 & Pregnant and went on to star in Teen Mom. The two share daughter Carly, 16, whom they placed for adoption in 2009, as well as daughters Rya, 3, Vaeda, 6, and Novalee, 10.

This past April, the couple candidly discussed their struggles with Carly's parents, Brandon and Teresa, on an episode of PodcastOne's Cate & Ty: Break It Down. The Teen Mom alum, 33, and her husband opened up about the reason they haven't had a visit with their daughter in two years.

"I posted a picture on my Instagram. It was like all of us walking and it was the back of us, and then Tyler posted one, where it was him, Carly and Nova, and it was the back of them," she explained, noting the last visit they had was two years ago. After the visit, they had a conversation with the adoptive parents, who told them the reason they were upset with the photos.

"We had the conversation, I said, 'You’ve always told me if it’s the back of her head it’s fine,' ” she continued. “It was actually Brandon who said, 'Well, I guess we’re just kind of upset about it because now MTV can’t pay us.'"

Tyler quickly added, “because it’s not an exclusive picture [and] because we did it first.”

The two have discussed Carly's parents pulling away and cutting off access to her in recent episodes of Teen Mom: The Next Chapter. Catelynn and Tyler said that sending occasional gifts to their daughter was deemed "out of control and inappropriate."

Catelynn explained to producers that they would send updates every few weeks on what's going on with their girls. However, Tyler noted that many of the messages appear to have never been delivered.

The couple then realized that Carly's parents blocked Catelynn. Tyler suggested they talk to their longtime adoption counselor, Dawn, about how to navigate this. Frustrated, he lamented, "You're closing the open adoption with no explanation as to why."
