Heidi Klum and Vito Schnabel are officially calling it quits.
The German supermodel, 44, tells PEOPLE: “I believe that it is important to take time to pause and reflect.”
Klum was far from down as she jetted to Las Vegas for the weekend, looking radiant as she introduced 30 Seconds to Mars at the iHeartRadio Musical Festival. On Saturday, she then caught Jennifer Lopez‘s All I Have Sin City show, sharing a backstage photo on Instagram.
“Love you @jlo …❤️Your show was absolutely AMAZING #vegas #allihave,” Klum wrote.
She also mingled backstage with friends David Foster and David Ghetta.
“She’s flying free” a source said, who adds the mom-of-four was happy to let her hair down with her girlfriends in Vegas.
Earlier this month, a source told PEOPLE that Klum and Schnabel, 30, were “taking time apart.”
“Things have been difficult recently, they live on opposite coasts,” the source said at the time. “And it’s the start of a school year and Heidi has to concentrate on the kids.”
