 Knowing that the Spice Girls were formed by an advertisement in The Stage , Diamandis applied for auditions listed in that newspaper . She travelled for several unsuccessful auditions , including opportunities with the musical for The Lion King and a boy band organised by Virgin Records , during which she managed to leave her CV to an A & R Representative , but was unable to audition at the time of the appointment as she felt sick . In 2005 , she created the stage name " Marina and the Diamonds " ; after coming to prominence , " the Diamonds " was established as a reference to her fans , instead of her backing band .
