The 41-year-old singer-and-actress believes confidence comes from feeling valued, so she always tries to stop herself from thinking negative thoughts about herself.
She said: ' know it's hard for women to tap into that feeling of self-worth. We need to get the message out that you are valued, you are a goddess and don't forget that.
't's about stopping those thoughts of negativity and insecurity.
' think changing that and really recognising yourself triggers control of how you feel, so you're able to go, 'No, I'm awesome man, I'm amazing, there's nobody like me.' I think that's the big secret to body confidence.'
Despite her positive outlook, Jennifer admits she can't help but worry about negative opinions and responses to her work.
She told Britain's Cosmopolitan magazine: 't's easy to let negative stuff get to you. I'm no different to anybody else.
'f I'm performing for 200,000 people and there's one person near the front row who's not enjoying themselves, it'll be that one person who's going to bother me.
'That's why it's important to remember you're special, so those messages register more than the few negative ones.'
