Jessie J

My attitude goes back to my childhood. I used to audition for theatrical roles, and you can't stand out in a room full of ambitious eight-year-old girls by acting the wallflower. I realised then that I couldn't do things half-heartedly.

I have friends of mine that are actors or singers, and they're the classic guys where, they're onstage, and they're like, 'Okay, the blonde in the third row, seat 24, bring her to my dressing room.' I've never, never taken advantage of that, I swear to God.
