For those who don't know, Anthony is a big Katy fan. He has cancer and only a few months left to live. He made a bucket list and one of them was to meet Katy Perry. KatyCats tried to get her attention and it worked, she contacted him and is flying him down to come with her to the VMA's. He's also married now.
Good God that video in the op got me chocked up. I can't believe such a healthy looking person has a ticking bomb inside of him. I am so proud of Katy for helping out such a person.
