NEW YORK, NY - JULY 11: Actress Ariana Grande attends the New York premiere of 'Harry Potter And The Deathly Hallows: Part 2' at American Museum of Natural History on July 11, 2011 in New York City.
Ariana Grande- singer and known Harry Potter fan - turned 23 last week. She celebrated by partying with much of the cast of "Victorious." Her friends made a Harry Potter rap music video in her honor, which the singer posted on Instagram.
It's pretty amazing. Her friends, who don't seem to know much about Harry Potter, dress up in Hogwarts outfits and wrote a rap song about it anyway. They even use a segment of "Hedwig's Theme," from John William's movie score, as part of the beat.
