PHOENIX -- With just hours to go until he's face to face with his dream girl, Matt Peterson is getting ready for what is sure to be the most memorable night of his young life.
The Arcadia high School student made headline earlier this month when he made a video in which he asked Miley Cyrus to prom. He posted the video on YouTube and it went viral.
"I've been obsessed with her my whole life," Matt Peterson told 3TV's Yetta Gibson. He even had the chance to meet Miley when she was in town for a radio gig in 2009.
Miley responded to Matt on Twitter. While she said she would not be able to go to prom in May, the star invited him to hang out with her at her Phoenix show -- tonight. "Don't forget a corsage," she wrote.
Dear Matt Peterson, I don't think I'll be able to make it to prom BUT why don't you come to my AZ show & hang w me? Don't forget a corsage��— Miley Ray Cyrus (@MileyCyrus) February 8, 2014
Matt was already planning on going to the concert at U.S. Airways Center. Now he'll have a national audience at he gets ready and goes backstage with his favorite star.
He's been counting down until today, even putting together a special outfit -- a "tongue-xedo." (It's a Miley thing.) The tongue-xedo is in his closet and ready to go, but he wouldn't show it to Gibson. He did, however, show off the tie as he told her about his creation.
"It has tongues head to toe," he said. "It has 163 tongues on it. ... The back has a little tribute to my video, as well."
To say Matt is stoked for tonight is a bit of an understatement.
"I'm freakin' out, " Matt told Gibson Thursday morning, hours before setting off for his backstage-with-with-Miley-Cyrus adventure. "I did not sleep last night. ... Prom's just coming early for me. Prom is tonight."
Kathy Peterson, Matt's mom, said she's really excited for her son and that Miley has been was so nice to him when they met in 2009.
At that first meeting, Matt was so excited he cried.
"That's like the sweetest thing ever!" Miley said with a laugh during the radio show.
"I appreciate the way Miley has treated him," she told Gibson. "She goes over and beyond being nice."
There's only one rule Matt has for tonight -- no crying.
And the corsage? Matt said he's picking it up on the way to U.S. Airways Center. He's hoping for a dance with Miley. And possibly a hug. And -- dare he hope? -- a kiss.
Thursday night's concert is part of Cyrus' Bangerz Tour.
