Though Luann and Garth were seemingly hot and heavy during the fall, the two did part ways by the end of 2020. 

Reports began circulating on the often-anonymous gossip Instagram account, @DeuxMoi, that Garth was cheating on Luann with someone in the Hamptons in the spring of 2021. The "Money Can't Buy You Class" artist stated that Garth couldn't be cheating on her because the two had already broken up. 

"Garth and I stopped dating before the holidays and I only wish him well," Luann shared in a statement to Page Six. 

Though Garth and Luann were no longer an item, the JULUKA Fitness also shot down that he was in a relationship with a woman in the Hamptons.

"Regarding this girl, we have no relationship," he told Page Six in the same article. "She came to my exercise class once. We follow each other in Instagram and that is it."

Shortly after the mom of two confirmed her breakup from Garth, the rumor mill began churning once again about her relationship status.

A source close to Luann told Us Weekly that the reality star had already "moved on" from Garth.

"She's since moved on. She met a guy when she was on vacation recently in Tulum," the insider shared in April of 2021. "She was spotted having fun with her new mystery man in Mexico, and she's completely smitten by him."

Could the aforementioned mystery man be making a cameo on Season 14 of RHONY?

The Real Housewives of New York City airs on Tuesdays at 9 p.m. ET on Bravo.
