Heidi Klum Leaving Katy Perry Concert in LA Pictures

Heidi Klum Rocks Out to Katy Perry With Leni and Henry

Leni, Heidi, and Henry wore glow-in-the-dark glasses.

Heidi Klum was in great company last night when she took her oldest kids, Leni and Henry Samuel, to Katy Perry's LA concert. The threesome looked like they had a great time and were still wearing their glow-in-the-dark glasses for the car ride home. It's the second time Heidi's been treated to a Katy Perry performance this week. Heidi and Katy were both at Sunday's AMAs, where Katy sang and danced to her latest single, "The One That Got Away." Heidi had the honor of introducing the singer, and said that she and her whole family love Katy's tunes.

With Thanksgiving one day away, Heidi's also gearing up for Christmas! She got a head start on decorating a tree Monday at the QVC headquarters. In typical Heidi fashion, her ornaments were extrachic as they happened to be items from her new jewelry line, Wildlife.
