The pregnant singer has reportedly been inundated with offers from top stores to launch a maternity clothes line but she says she's not interested.
"My demographic is generally young girls," Lily, 22, told the BBC. "I don't think a maternity line is particularly suitable."
Lily announced she is expecting her first child with her boyfriend Chemical Brothers star Ed Simons,37, after having only been dating him for three months.
Lily launched her own line with high street store New Look last year but is unlikely to working with the chain on a maternity range.
