Sophia Bush insists she isn't perfect.

The 'Chicago PD' beauty admits she only recently started to embrace her body and feel confident about her looks after years of insecurity.

The 31-year-old actress told the 'Today' show: ''I've spent so much time talking to women about, 'Hey, I may be on TV and I may be photographed for magazines, but I don't think I'm perfect. I don't wake up in the morning and look in the mirror and go, 'Hey, I'm amazing!' That's not how it is, I'm a women and it's a struggle for all of us.

''And it took me until this point in my life at 31 to say, 'Hey, yeah I'm going to embrace my body and own it for me, not anyone else. And I'm curvy. I'm not some rail-thin, 6-foot-tall runway model who was just born that way. I was born like this. And that's A-OK. And the conversations that have sort of come out of that, the conversations about feeling empowered in our skin rather than comparing ourselves to other women have been a really great by-product actually of that whole shoot.''

The former 'One Tree Hill' star works with the charity, I Am That Girl, which works to encourage girls to feel strong, secure and beautiful in their own bodies.
