But the truth is we just weren’t getting along.” Robin Marchant/Getty The couple, who wed in a Palm Beach ceremony on New Year’s Eve, both filed for divorce on Thursday, Page Six reported, with Luann making the announcement of their separation on Twitter. “It’s with great sadness that Tom & I agreed to divorce,” the former countess wrote. “We care for each other very much, hope you respect our privacy during this sad time!” Hours after sending the tweet, the 53-year-old reality star was spotted out in Sag Harbor, New York, without her wedding ring — wearing a yellow sundress, matching sandals, black shades and carrying a brown purse.
