"The claims that have been made are a misinterpretation of an entirely innocent situation," Schnabel says. "There is nothing more to this than I was simply saying goodnight to a family friend and we went our separate ways."
Schnabel and Klum, who have been together since 2014, are still together, according to their rep.
In an interview with ET in February, Klum told ET that she's very romantic with her younger beau.
"I'm very romantic and old fashioned," she said, before teasing their Valentine's Day plans.
