Katy’s performance of her new single ‘Firework’ definitely wasn’t her best, but the singer says it was all ‘nerves!’

Katy Perry‘s pipes weren’t as off the hook as we’d hoped, but the 25-year-old showed off her awesome figure in a super-tight black sparkly bodysuit Oct. 17 on X Factor where she performed her new single “Firework” … but she did sound a bit shaky. The global phenomenon took to her Twitter to explain to fans that her subpar performance was simply due to stage fright!

“Oh my gawd I was so nervous,” she tweeted. “Thanks #xfactor for making me feel like I was actually one of the contestants :)”

We’re guessing the nerves were partly because her fiance Russell Brand is from the UK, and she had a lot of pressure to represent! Either way, we’re sure her soon-to-be hubby was too busy fixated at how HOT his bride looked — especially because she’s supposedly denying him sex until their wedding Oct. 23! The two are set to be married at Rambagh Palace in Jaipur, India in front of family and friends.

“We love each other and we want to get married in front of our friends and family and keep it very normal,” says Russell.
