Inside Lady Gaga's Super Bowl Halftime Show: 'I've Been Planning This Since I Was 4'

"This is where I'm supposed to be!"

Lady Gaga promises a blowout performance when she hits the Pepsi halftime show stage at Super Bowl LI.

"It will be special, because, you know, I've been planning this since I was four," Gaga exclaims in a behind-the-scenes look at how she's preparing for the big day. "So, I know exactly what I'm going to do."

"For me, it's about giving to the fans and bringing people together that wouldn't normally come together," Gaga adds of her upcoming Super Bowl Sunday performance. "The thing is, it's such a big world stage in terms of how many people see it, and it's been done so many times. I think the challenge is to look at it and say, 'OK, what can I do differently? How can I elevate certain little things here and there, and also make it about the music?'"

Gaga also shared on Instagram on Monday that she is going all out in preparation for her big performance. "Super Bowl Rehearsal is so fun. We built a tent in my backyard with a dance floor to practice!" the 30-year-old pop star wrote. "We love you monsters, can't wait to perform for u!"
