The 23-year-old singer insists she is "free" with her body and would be comfortable stripping off for a film role or photo shoot if she believed in the project.
She said: "I`d strip off if it was done tastefully. I`m quite free with my body. But I`ve not got everything out! I`m quite comfortable in my own skin and I`d think about an offer. It just depends on what kind of thing it would be."
The `Skinny Genes` singer - who was signed to London-based modelling agency Select Models earlier this year - also revealed she doesn`t hit the gym to keep in shape, because she is just too busy with her pop career, but luckily her hectic lifestyle keeps her trim.
She explained: "Once my work schedule got busy I didn`t have time to work out. But because it is so busy I`m always on my feet so I haven`t put any weight on."
And Eliza doesn`t panic about what she looks like before heading off on her summer holiday.
She laughed to BANG Showbiz: "I don`t prepare for wearing a bikini, I always have a bit of a tummy."
