Jesse McCartney : (2) " I get insecure about a lot of things. In my line of work, unfortunately, your appearance is important, and I’m always like, ‘Am I going to the gym enough this month? Have I been taking care of myself?’ I get insecure about things from time to time. " - Jesse McCartney " When I’m singing, that’s all me. That’s from the bottom of my heart – it’s everything I’ve worked for. When you’re on stage, there are no guidelines. No one’s telling me what to do! " - Jesse McCartney
