Elder Ordonez/INFphoto.comRamona Singer is moving on after filing for divorce from her husband, Mario Singer.
The Real Housewives of New York City star stepped out without her wedding ring on Thursday, Jan 30, in New York City.
The 57-year-old businesswoman looked casual as she took her dog for a walk in the cold temperatures, sporting a puffy jacket and skinny jeans.
Singer's decision to divorce her husband comes just one day after it was revealed that the couple had separated after 22 years of marriage. They have a 19-year-old daughter, Avery.
Singer confirmed the breakup news via Twitter on Jan. 29, writing, "Thank you all for the love & support! For my daughter's sake, I would appreciate everyone respecting our privacy during this difficult time." Six days earlier, she denied her marriage was on the rocks. "Everything is good," she told E! News at the Ramona Singer Wine dinner at David Burke at Bloomingdale's. "Everything's good!"
Rumors had been circulating for months that Mario was carrying on an affair with a 27-year-old named Kasey Dexter. "Ramona had no idea about Kasey until the [New York] Post ran the story about Mario getting another woman pregnant over the summer," an insider told E! News on Wednesday, Jan. 29.
This past weekend, Ramona reportedly caught Mario spending time with his girlfriend at the couple's Hamptons home. "She saw him there with the girlfriend and made a big scene and called the police," a source told People. Even so, "She did not want a divorce. Ramona loves her life. She loves Mario."
Mario, who manufactures religious articles and trophies, has yet to address rumors of his infidelity. Ramona, meanwhile, did not return E! News' immediate request for comment.
Season 6 of Bravo's The Real Housewives of New York City returns on Tuesday, March 11, at 9 p.m.
