Motley Crue rocker Nikki Sixx's new clothing line is to expand and include jewellery and a women's line. The rocker launched his Royal Underground menswear line last year (06) and it's already a big hit, so he and partner KELLY GRAY are looking for ways to expand their business. Gray, the former chief executive and model for women's luxury label St. John, which was founded by her parents, will design a new collection of women's leather jackets, cashmere sweaters, dresses, skirts, T-shirts and jeans, while Sixx is behind a planned new jewellery line.
