Katy Perry is now getting nervous ahead of her Super Bowl performance this year.
The singer's going to take to the stage for the famous half-time show at the championship game next month and confesses she still can't believe she was chosen for the headline gig.
Speaking to ESPN The Magazine Music Issue, Katy said: "Honestly? I feel like I've outdreamt my dream. I don't get nervous much, but I'll definitely be a little tingly inside that day."
Katy will perform half way through the game between the Seattle Seahawks and the New England Patriots at the University of Phoenix Stadium in Arizona and Houston Texans' J. J. Watt - who appears on the cover of the magazine with Katy - admits he's jealous she's involved with the end-of-season match.
He joked: "She's playing in a bigger game than I've ever gotten to play in. I'm hoping someday to be in those shoes."
Following in the footsteps of Bruno Mars - who last year performed before 115 million viewers - she'll be joined onstage by Lenny Kravitz.
Idina Menzel is also to perform the National Anthem before kick-off on February 1.
