Some celebs you just get nervous before they perform or you worry.
for example: I used to worry so much for Rihanna. i loved her so much and would worry when shed perform but ever since 2010's AMA performance, X Factor UK "What's My name?" and Brit Awards medley (all in 2010) I stopped worrying. I felt at ease. She now owns every performance.
With Beyonce I never get butterflies of nerves or anything. I am so comfortable when I watch her because I expect nothing less then perfection all the time.
Katy gets me really shakey sometimes. I really worry and get nervous for her. Same with Ariana Grande. (i love them especially Ari)
Lady Gaga gets me hyped up lol! like im here for her mess, her slayage and her bad. idk y
the list goes on
how about yall?
