BARRANQUILLA, COLOMBIA: Actress Sofia Vergara has put her wedding plans on hold. According to a new report, Vergara’s relationship with fiance Nick Loeb is over - and she was spotted out in late November without the giant sparkler on her left hand. “She and Nick have been having problems since this summer, and they’ve been spending more time away from each other,” a source told In Touch Weekly magazine. The pair apparently didn’t spend Thanksgiving together. “He wasn’t with Sofia,” a source close to him admitted. “The fact that Nick wasn’t with her family on Thanksgiving speaks volumes.”–SH
