The 32-year-old Playboy model, who is famous for her fuller figure, said her curves symbolise happiness in life, eported Contactmusic.
"I love my body. The curvier I am, the happier I am. I think that's true of most girls. When you've got a lovely boyfriend you just eat cake and kiss on the sofa. It's lovely!," she said.
Brook said she is completely satisfied with her image.
"I think I'm a size zero until I see pictures of myself and realise I'm not!," she added.
