I was terrified before Super Bowl performance: Katy Perry

Singer Katy Perry says she was more cautious about performing at the prestigious football championship, Super Bowl than any of her personal shows.
Perry, 30, took to stage at the inaugural ceremony of the Super Bowl XLIX, reported Us magazine.
"In my show, I am boss daddy. I am boss mommy," Perry said.
"They call me Boss. Everything goes through my eyes; I call all the shots, 100 percent of it. With the NFL, I have to be accountable to several levels of red tape. There are many committees I have to go through for my costumes, the budgets of my show, every interview- everything, I have to report to somebody. So I am no longer the boss; I have to relinquish that control," she added.

Perry said after committing to the halftime show, she trained arduously day in and day out to successfully deliver a worthy performance.
"We love this opportunity, but once you decide you're gonna do the Super Bowl, you're gonna have no life for six months. It is the biggest thing. Anyone that's ever done it has been scared. You stay off the Internet for the five days afterward.
