“We’re about to become a family of three,” the post read as the couple held onto a Christmas onesie. “So happy to share that we’re expecting. Baby Radtke coming soon.”

In a separate TikTok post, Radtke seemingly responded to backlash about the pregnancy, stating that he is employed. He captioned the video, “Yall redditors are weird as hell!”
Catelynn Lowell and Nicholas Radtke MTV/FacebookBack in 2021, Radtke appeared on an episode of Teen Mom when he talked to Lowell, 33, about safe sex.
“There’s a lot of information about sex online, but a kid still needs advice from people who love them,” Lowell explained on the MTV reality show. “I want to make sure Nick knows he can come to me whenever he wants.”
While Lowell admitted to having sex at 14, Radtke told his older sister, “I’m completely different from you.”
Lowell replied, “I just want you to know the right things to do when the time comes so that way, you don’t have to end up in something like I was in.”

While Lowell once had a strong relationship with her brother, things have seemingly become more distant over the years.
In an August 2023 Instagram post, the Teen Mom: The Next Chapter star cautioned her followers against fully supporting her sibling.
“My brother is continuously just trying to build this ‘fan base’ that’s based off of lies!” she claimed via social media at the time. “If he wants to use my name for clout & to get followers, it is what it is, but I at least want those people to know who they’re following & what type of person they’re actually supporting! ?♀️.”

In January, Radtke appeared to confirm things still aren’t good with Lowell and Baltierra, 33, when he posted a video via Instagram that read, “You know it’s bad when people on the internet feel more like siblings than your actual siblings.”
As Radtke and Smith prepare to become parents, both parties appear focused on the positive support around them. They are also interested in sharing more about their road to parenthood.
“I’m thinking of doing YouTube videos again this time focused on ‘dad’ content and showing my life whilst raising a baby,” Radtke wrote via his Instagram Story on Tuesday, December 30. “Would y’all watch?”
