The star has been the lead singer in the 'Ain't It Fun' rockers since they formed in 2004, but even a decade later she finds herself struggling with the attention being on her rather than the rest of the group.
She told Rolling Stone magazine: ''I'm still surprised when I feel uncomfortable with it after 10 years.
''It's funny when I feel left out, or in the cold, and everyone's focusing on me. Onstage, it's so much about the music that I feel comfortable.
''But being the frontwoman is not an easy job, it's something I'm really proud to be getting better at; performing really well, singing really well and speaking to the crowd - that's the part I'm most nervous about, like ''What do I say that makes me sound cool?'' - but also trying to keep it the same way that it felt when we were in clubs.''
Although Hayley might be seen as the face of Paramore - which is completed by Taylor York and Jeremy Davis - but the public perception is something she struggles to accept or change.
Asked whether being the focus is an issue, she said: ''You know, it depends.
''[Sometimes] we do TV spots, interviews, and we spend tons of time talking and you think that it feels very evenly spread out, you think that it feels deep and the questions are nice, and then it gets edited and then it's just you, and it's just asking about your hair.
''That's the stuff that I get uncomfortable with.''
'Peep Show' may be dead, but Mitchell & Webb are not.
