Custodio first revealed she was expecting a baby in November.

"So excited for our new adventure," she wrote alongside several photos with Obscura. "Words aren't enough to tell you how wonderful you are, I'm forever grateful for the happiness and joy you have brought into my life, and for make [sic] one of my biggest dream come true🤱🏻, we can't wait to meet you."

She continued, "I am the luckiest woman to be able to call you mine @ben_obscura ✨❤️."

Custodio's baby news came just over a month after she split from her ex-husband, Michael Jessen, on the former couple's two-year wedding anniversary.

"Today is only our second wedding anniversary and, sadly, our last," Jessen wrote alongside a photo from the couple's wedding. "Our marriage is a Covid-19 casualty that will not be showing up in any statistics. Thankfully, you are quickly emerging healthier and stronger than ever. Some of the rest of us will likely be staying in intensive care for quite some time."

In her own post, Custodio wrote a lengthy letter back to Jessen. She began by saying that, while the COVID-19 pandemic played a factor in their split, "we all know that there are more [reasons] than that.

The pandemic was "a hard time" for Custodio, she said, but "the hardest part for me was to picture you as someone that would be by my side, and unfortunately you showed something completely different."

She concluded her message by encouraging others who are not happy in their relationship to "stand up for yourself."

Jessen and Custodio first appeared on season seven of 90 Day Fiancé in 2019. The pair met at a yacht party in Croatia and were engaged a short time later. Jessen's ex-wife, Sarah, officiated the couple's wedding.
