Jessie J has compared being a pop star to being in 'Big Brother'.
She told The Daily Star: 'Being a pop star is like being in Big Brother.
'I'd be a liar if I said I didn't cry every now and again and get scared.
'I'm 22 and the amount of expectation on me at the moment is mega. I'm so tired and I think, 'can I even do this?'
She also added that she doesn't take her success for granted.
'I know a lot of people who are really talented that don't get any attention, so I'm not going to take it for granted. But I'm also not going to apologies.
'I have worked my butt off for six years. I actually got a bit tearful thinking about it the other day. I've done a hell of a lot, and been rejected a lot.
'I have to embrace this time, no matter mad it gets. Your journey is way more important than your destination.'
