The former lovers sparked rumors of a rekindled romance on Monday, January 14, when the Southern Charm star, 28, posted a shot of her standing next to Ravenel, 57, at a party.
PEOPLE later confirmed the exes are getting cozy again.
“Thomas and Kathryn have been spending a lot of time together,” a source told the publication. “They’re on really good terms. It started with co-parenting, but it quickly grew into something more.”
“She feels comfortable with him again, and they’ve both kind of tossed aside any other relationships they had for each other. There’s that spark, and they’re letting themselves explore it right now,” the insider added.
