Katy Perry finally announced the winner of her “Good Morning America” “Roar” high school video contest: Lakewood High School in Lakewood, Colo.

“It was so incredibly crafted and all different type of school clubs did their own individual things,” Perry says of why she chose that video, above. “I give a big round of applause to whoever organized it, because that was thousands of kids coming together to roar.”

Perry was especially impressed with the fact that this video was filmed with one shot, but she says she loved every submission she got to screen. The difference with the Lakewood High video was that she felt it “really embodied a whole school spirit. I think that they brought everyone together.”

To celebrate Lakewood winning the contest, Perry will perform at the high school on Oct. 25 (which, incidentally, is her birthday). She currently is filming her new music video for “Unconditionally” in London. But Perry had another gift for a student who participated in the contest.

Perry also announced that she will honor Verrado High School student Megan Squire, a 17-year-old with Down syndrome who was the focus of the Buckeye, Ariz. submission, by taking her to a “special event” in the fall as her date.

“I just want to celebrate her and hear her roar in person,” Perry says. “Megan, thank you so much. I love you. I love your spirit. You have really inspired me.”
