Heidi Klum has called it quits with boyfriend Vito Schnabel. The 44-year-old model and television personality confirmed her separation from the New York art dealer in a statement Monday to People. "I believe that it is important to take time to pause and reflect," she told the magazine. The breakup follows rumors Schnabel was unfaithful to Klum over the summer. The art dealer denied cheating in June after the Daily Mail published photos of him appearing to kiss another woman in London. "The claims that have been made are a misinterpretation of an entirely innocent situation," he told People at the time. "There is nothing more to this than I was simply saying goodnight to a family friend and then we went our separate ways." Klum kept busy over the weekend, attending the iHeartRadio Music Festival on Friday and Jennifer Lopez's Las Vegas residency show Saturday. She shared a photo with Lopez the next day on Instagram. "Love you @jlo ... Your show was absolutely AMAZING #vegas #allihave," the model wrote. Klum previously dated bodyguard Martin Kirsten, and was married to Seal from 2005 to 2015. She shares four children, 13-year-old Helene, 12-year-old Henry, 10-year-old Johan and 7-year-old Lou, with the singer.
