Hours earlier, Lowell teased the arrival of their latest addition by revealing she was in labor. "Baby R is on her way ❤️ send positive vibes 💕🥰 @tylerbaltierramtv," she posted.

Lowell and Baltierra first announced that she was expecting a baby in a February Instagram post, about two months after revealing that she had suffered a miscarriage.

"This rainbow was worth the storm. Baby Baltierra coming soon," she wrote in the caption of the post.

For the announcement, Lowell posted a picture of Nova and Vaeda posing with a sign that reads, "27 weeks until I become a big sister." The mom also shared an ultrasound of her baby on the way, as well as a photo of a positive pregnancy test.

Lowell added to Celebuzz that she was "definitely surprised that we got pregnant so fast with this baby."

A few days later, she revealed the sex of the baby to the same outlet.

"We have found out that we are going to be having a … drumroll please … another girl!" Lowell told Celebuzz. "While we wanted a boy since this is our last, as long as she's healthy ... that's really all that matters. This is our last and final but we know one day we will have a grandson and adore him!"

"We are blessed to be able to have another baby to love and raise," she continued. "Especially after our miscarriage, we are so grateful!"
