A seventeen-year-old Campus High School senior named Katie was at work Thursday night when she received a surprising phone call from her sister.

“Colton just opened your box on national television,” said Katie's sister. “I was just like, this is some kind of sick joke. You’re joking.” Her sister responded that she was serious. “I just stared jumping up and down, was like, oh my gosh, oh my gosh." 

Earlier, Katie sent a package to American Idol contestant Colton Dixon asking him to go with her to her high school prom.

She didn’t have a date so she bought a life-sized Justin Bieber cut out, dressed up in her prom dress and took photos of herself along side the cardboard teen heart throb looking upset.

Katie then pasted a picture of Dixon’s face to the cardboard Bieber and posed happily for the camera.

She sent the pictures to Dixon in a shoe box with the simple message on the outside that read, “Prom?!”

“I didn’t think this was going to go anywhere,” said Katie. “[I thought] at least if he would see it, he would get a laugh out of it, let alone have it opened on national television.”

When Katie got home from work, she watched the clip of Dixon opening her box on American Idol about four times she said and called the experience surreal and shocking.

Dixon said it was a “strong maybe” that he will attend her prom and has until April 28 to give his final answer. He sent a message to her via Twitter last night saying, “Hey! I'm flattered! Thanks for the awesome box, and the Beiber cutout is hilarious! Hope to meet you soon!”

Katie says she thinks Dixon has “has amazing talent” and is hoping he agrees to be her prom date.

“Oh my gosh, I would be ecstatic,” says Katie. “I don’t even know what I would do. I hope he says yes.”
