Ch-ch-check out Obama's AH-Mazing final WHCD speech (above)!
There are millions of Harry Potter fans around the world.
But superfan Katie Aiani just may be the biggest!
The 26-year-old has been obsessed for the last 15 years, building a remarkable collection, including toys, costumes, pillows, and props, worth an estimated $70,000!
"My Harry Potter obsession began when I overheard the words 'Alas! Earwax.' My dad read the first book to my younger sister and at first I teased her for choosing to read such a silly sounding book.
But she demanded that I read it, so I decided to give it a go and I finished it in one night. I picked up the second and third books straight away. I got so drawn in by the story and the magic that I was so upset when I found out the fourth book hadn't been published yet.
From there I attended the midnight book release parties, then the midnight movie release parties and conventions. And I travelled to film locations, Quidditch matches, world movie premieres, Potter fan events - everything you could possibly think of…
I began collecting everything, and my friends and family have bought items for me every year for holidays and special occasions. My collection is priceless to me and will never be for sale."
Katie's megafandom culminated in the moment she received her own Hogwarts letter - of a sort anyway.
J.K. Rowling herself wrote Katie two years ago with words so inspiring she got them TATTOOED on her arm:
"Keep fighting! You're inspirational. With Love & admiration -Jo"
Sounds like a Gryffindor to us! Watch the video (below) to see the amazing moment she opened the letter!
