Lorde - The 'Royals' singer admitted to The West Australian that her stage fright can be so severe that she gets sick. "I, like, totally threw up before my show last night. I am reduced by nerves. I can be completely crushed by feelings of all kinds [...] I get nervous, I get freaked out, I get, you know, the usual stuff."

She added, "My nerves don't really settle until I'm offstage." But she shared she once was having an anxiety attack because she was about to meet Beyoncé but then Queen Bey walked in and told her, "When I listen to you I feel like I'm listening to God." That'll cure anyone's nerves!

Jennifer Lawrence - Talking about her anxiety, J-Law told the New York Times, "I have a prescription. I find a certain peace by thinking of 'me in public' as sort of an avatar self.

Jennifer Lawrence - Unfortunately, she doesn't think it's ever going to be easier. She told E! News, "I never feel like, 'I've got this.' I'm always very nervous and aware of how quickly people can hate you and that scares me."

But it's OK; you pick up and just move on."
