The actress' part in the fictional McKinley High New Directions Glee club has made her feel beautiful.
The 24-year-old told Marie Claire magazine: 'Glee has made me feel beautiful, now when people say that I don't feel like they're lying.
'Glee has shown me that I am beautiful, that I can be beautiful not matter what I look like, what my weight is.'
Lea, who has a total of nine tattoos, added: 'When they always talk about my boobs being too small I'm like OK, if we're going to talk about this then let's be real – Rachel doesn't have the smallest boobs in the club, although that wouldn't be a problem if she did, but they keep saying she does and I'm like, 'It's not true!''
'But they always say I have a great butt, which I really do like.'
