Thomas and Bailey, 52, called it quits in 2016 after tying the knot on an episode of the Bravo franchise in 2011. The former couple’s divorce was finalized in 2017.
Bailey and Thomas have had a peaceful split and have remained close friends. He also still appears on the popular Bravo program.
Fans of the show even thought there was a chance the couple would reconcile as they took a trip to Hawaii together.
However, Bailey insisted “that ship has sailed.”
“I know it seemed like we just decided to go to Hawaii together, but I was invited by Kandi and he was invited by Todd. We had an amazing time together,” Bailey previously told PEOPLE of the 2017 trip.
“It was a little awkward at first but we were still technically married in Hawaii,” she said. “So that got a little confusing. If I wanted to take one last lap around the pool, it’s not like it would be that big of a deal because we were technically still married. But I didn’t want to confuse the issues at that point. Had I been I asked, I would have graciously declined to keep things uncomplicated.” Bailey also revealed the two were still in a “great place.” RELATED: Real Housewives of Atlanta‘s Peter Thomas Is Going to Be a Grandfather! “I’m really pleased with the way we handled our divorce,” she said. “I did not want to be mean, or ugly, or ratchet about it.
