Eliza Doolittle is a ''free, naked wild-child''.

The 26-year-old pop star is so comfortable in her own skin that she rarely wears a bra and admits she would happily pose naked for an artistic photoshoot.

She exclusively told BANG Showbiz: ''I don't really wear my bra too much. Sometimes I do. If I feel like my back hurts, I'll wear a bra, otherwise I'm about being a free, naked wild-child.

''I'm quite a free spirit. I've not posed naked for a magazine before, but that's not because I'm against it or anything. I just haven't yet.

''I think you have to just do what you feel comfortable with doing. I would always just do whatever I felt comfortable doing as long as it wasn't trashy.''

Proving to be quite a feminist, the 'Pack Up' singer doesn't like how the female body is oversexualised.

She ranted: ''I don't like how women's bodies are Page 3 news. I just don't think that's big news. Women's bodies are women's bodies and that's that. And I love to see beautiful, the female form in great art and great photography.''

Eliza even noted that she approves of the Free the Nipple campaign that is championed by the likes of Cara Delevingne and Scout Willis, despite not really knowing much about it.

When asked if she supported the cause, she laughed: ''I haven't read much about that but I mean, just the title of it. Definitely!''

Eliza performed an exclusive set at Argos' new digital store at 216-217 Tottenham Court Road in London on Sunday (27.07.14).

The singer serenaded a select crowd with songs such as 'Big When I Was Little' and 'Let It Rain' to mark the launch of the store.
