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.

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.” Klum just recently wrapped up season 12 of America’s Got Talent, where she serves as a judge. Last weekend the supermodel headed to L.A. where she walked the red carpet at the 2017 Emmy Awards solo.
