Kailyn Lowry was just 17 when she and high school boyfriend Jo Rivera welcomed their eldest son, Isaac Elliot Rivera, on Jan. 18, 2010.
And though they split a year later, the exes have settled into a comfortable co-parenting arrangement. “We’ve come a long way since we were 18,” Kailyn wrote on X after attending Jo and now-wife Vee Rivera‘s 2018 wedding. “I couldn’t ask for a better stepmom.”
As for her oldest son, “We have literally grown up together, but in some ways he’s even more grown than I am,” she wrote in an Instagram tribute on his 13th birthday. Describing the devoted Olivia Rodrigo fan, musician and basketball player as “thoughtful, brilliant, funny and at times a smartass,” the Delaware State grad praised his caring heart.
“I think what really inspires me about him is the way he challenges social norms,” she wrote. “Because he is curious and open-minded, he can form his own thoughts and opinions.”
Elliott, who announced his intentions to go by his middle name on his mom’s Barely Famous podcast in June 2025, while also coming out as gay, “accepts people for who they are and never how they’re ‘supposed’ to be,” Kailyn wrote. “More people should be like him.”
