Hayden Panettiere has finally accepted her looks after growing into her body.

The 23-year-old beauty insists she has learnt that having confidence about what she looks like is one of the most ''attractive'' parts of her appearance after previously being very self-critical.

She said: ''Others can tell when you're happy with being you and when you're not.

''As I've gotten older and grown into my body, I've started realising that the way you carry yourself and that light coming out of your eyes are the most attractive things about you.''

Hayden admits she suffered from body dysmorphia - a type of mental illness in which the affected person is concerned about their body image - for a while after a magazine printed a picture of her in shorts with the word ''cellulite'' stamped across the image.

Speaking to Women's Health magazine, she added: ''It gave me such body dysmorphia for so long. But I remember reminding myself that beauty is an opinion, not a fact. And it has always made me feel better.

''I now try to eat healthfully but I don't go crazy over it, but you gotta eat!''
