Parade compare themselves to the Spice Girls.
The girl group believe they have separate "roles" like the record-breaking British group - which featured Victoria Beckham, Emma Bunton, Mel C, Geri Halliwell and Mel B - but also feel they are very much like a family.
Band member Bianca Claxton exclusively told BANG Showbiz: "Oh we've definitely got roles. Jessica [Agombar] and Lauren [Deegan] are the older sisters. Kind of the business mind. Business Spice. Lauren is like a quirky one. Quirky Spice!
"Then we have two very naughty younger sisters, Emily [Biggs] and Sian [Charlesworth]. They shouldn't be allowed to sit together. They're both naughty but Emily gets away with it because Sian always takes it to the next level of volume."
Emily added: "Bianca is mummybee. Despite her being the youngest."
The band - whose new single 'Louder' charted in the UK top ten on Sunday (13.03.11) - also revealed they were so excited to first hear their debut track on the radio they stripped off and ran down a hotel corridor to celebrate.
Emily joked: "We've been in so many hotels recently and we always get told off for making too much noise. We streaked down a hotel corridor when we first heard it!"
