The MTV stars revealed they were expecting their third child to Us Weekly backin September, with Catelynn admitting the news came as a surprise.
“The big news is that we are expecting our rainbow baby. This baby is our rainbow after the storm. I’m super excited,” Lowell told Us. “It was a huge shock at first. We were not planning it, especially after the miscarriage and how I went downhill with my mental illness.”
She added: “We were going to wait a really long time. We were using protection and everything and still got pregnant. This baby just wanted to be here. It was very unexpected.”
Catelynn previously announced she was pregnant on an episode of Teen Mom OG last year, but just a few months later, the couple revealed she’d suffered a miscarriage.
After being diagnosed with post-traumatic stress disorder, Catelynn went to rehab in November 2017 to seek treatment for suicidal thoughts, and then again last January to overcome childhood trauma.
Catelynn, 26, and Tyler, 27, have been together for 13 years, celebrating their anniversary in July. Dating since middle school, the two welcomed their first child, Carly, in the first season of MTV’s 16 and Pregnant. They later placed her for adoption before welcoming daughter Novalee Reign in 2015.
