Heidi Klum has called it quits with boyfriend Vito Schnabel.
"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.
"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.
"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.
