Katy Perry joined in the Oktoberfest spirit Saturday in Munich, where she appeared on the European show Wetten, dass..? in a dirndl.
"I love lederhosen," the singer, 25, joked on the show, where she performed her hit "Teenage Dream," as well as "Edelweiss" from The Sound of Music, the latter while wearing her modern take on the traditional dress.
One European custom Perry has actually acquired? Cheering on her favorite football teams – with English fiancé Russell Brand's encouragement.
"I've adopted a little of the football thing myself," she admits. "I'm now a football fan!"
