When Lowell and Baltierra joined the cast of MTV's "16 & Pregnant," they decided they weren't prepared to raise a child and made the difficult decision to place their baby up for adoption.

In May 2009, their daughter Carly was born and placed with a couple named Brandon and Teresa Davis, who have chosen for their daughter not to appear on the show.

During season two of "Teen Mom," Baltierra found out that Lowell had lied to him about cheating with an ex two years earlier. This led to a short break up, but they quickly reconciled within the same episode.


In 2013, they called off their wedding.

While on VH1's "Couple's Therapy," Baltierra made the tough decision to call off his wedding to Lowell since they still had a lot of work to do in their relationship. Lowell said she was heartbroken but ultimately it seemed to help them both prepare to make a major commitment to each other.


In August 2014, the couple announced they were expecting their second child together.

Earlier that year, Catelynn told InTouch that she and Tyler made the decision to stop using birth control and they felt more ready to have a child now than when they were teens.

Just a few months later at 22 years old, Catelynn announced her second pregnancy.


Catelynn also got a new engagement ring in 2014.

On Christmas Day in 2015, Baltierra surprised Lowell with a new engagement ring. It's unclear if this was part of a second proposal, but the previously canceled wedding was clearly back on.


In 2015, they published a book they co-wrote together.

On August 22, 2015 - when Nova was just 8 months old - Baltierra and Lowell got married after being together for more than a decade.

Surrounded by their family, friends, "Teen Mom" co-stars, and even Carly and her parents, they vowed to spend the rest of their lives together.


In July of 2017, the couple launched a children's clothing line called Tierra Reign.

According to the site, the items are handmade in their home state, Michigan. And they're personally designed by Tyler and Catelynn.

As of April 2019, it seems the brand is no longer active.

In 2017, Lowell was dealing with suicidal thoughts and other mental health issues. And, around that time, she had a miscarriage. She checked herself into treatment twice and Baltierra stayed behind to look after Novalee and run their business on his own.


Divorce rumors started circulating in the summer of 2018.

Because of their struggles both together and apart, break-up rumors were rampant in the second half of 2018. Some of it has to do with the show - during the finale of "Teen Mom OG" that aired in April, Catelynn said she wouldn't blame Tyler for divorcing her.

Plus, fans speculated something when Catelynn changed the name in her Instagram bio from Baltierra back to Lowell.

But the rumors weren't true. "Tyler and I are not getting a divorce. Couples go through ups and downs. That's normal life," she told Us Weekly.


In September 2018 the pair announced they were expecting another baby.

In September 2018, Baltierra and Lowell announced their pregnancy on Instagram.

"We were not planning it, especially after the miscarriage and how I went downhill with my mental illness," she told Us Weekly. "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."


In November 2018, the pair announced that they decided to temporarily live apart.

On an episode of "Teen Mom OG," the two returned from couple's therapy and agreed to temporarily live apart from each other.

"Getting pregnant was very unexpected since we still have a lot of work to do on our relationship," Catelynn said in the voiceover, per People's reports. She explained to the show's producer that she and Tyler have been together for so long that they don't know who they are as individuals anymore.

The pair agreed that living separately for a bit could be the best thing to do. But, the couple isn't ending their relationship. "We don't want to see other people," Catelynn told the producer. "We're not getting a divorce or anything."


In February 2019, the pair welcomed their third child together.

According to Us Weekly, their third child was born on February 21 and they named her Vaeda Luma. Following their child's birth, the pair moved back in together, per the publication.


In June 2019, Catelynn said she thinks her and Tyler's temporary split was good for her but she doesn't need him.

On an upcoming episode of "Teen Mom OG" Catelynn speaks about how she believes her and Tyler's temporary split was a wise long-term decision.

"I think it was good for me, looking back at it now, realizing if he ends up wanting to divorce me, I guess, whatever. I'll be sad but I don't f-king need you. I can do this on my own," Catelynn said during an upcoming episode, per Us Weekly.

Recently, she also spoke about how she and Tyler have gone to couples' therapy in the past and it helped them and they are "in a good place."

"We're really opposite, but we have a lot of similarities. I just think really open, honest communication [works]," she told Us Weekly earlier this year. "I feel like some people are just meant to be with one another and I really just feel like that's him and I; we just really bond and click and connect."
