Throughout the first season of Southern Charm, Thomas continually discussed his desire to become a father. His wish to embark on a parenthood chapter has since been granted three times over.

In addition to having a 6-year-old daughter named Kensington and a 5-year-old son with Kathryn, Thomas welcomed a third child in the summer of 2020.

After months of speculation online, Thomas confirmed on his Twitter account and in an interview with Daily Mail that he had become a dad to son Jonathan Jackson on June 29, 2020. 

Jonathan's mom is Heather Mascoe, but Thomas has since noted that the two are not in a relationship.

"We are both very happy," he told the outlet. "Heather is a phenomenal mom and they're both doing well."

Following the birth announcement, Thomas said he is simply "really good friends with" Heather, and that the two dated for a short time in the summer of 2019. 

Though Thomas has continued to post content with Heather, he has not elaborated further on the nature of their relationship. It does appear, then, that the former reality star is single.
