Just another reason why Katy Perry is such an amazing artist to follow!!
Allie, a dedicated Katycat, suffered brain cancer and unfortunately passed away.
Saddened by the news, Katy paid homage by dedicating one of her concerts to Allie.
I hope you're finding peace up there on that pink cotton candy cloud. I dedicate this last show to u, sweet dreams angel #RIPKatyCatAllie
Before we knew it, #RIPKatyCatAllie was a trending topic on Twitter.
Aww…. so sad!! Our thoughts are with Allie's family and friends. We know it can't be easy right now…
Still, so so proud of Katy for paying such a wonderful tribute to one of her fans.
