The lyrics of "Me Plus One" detail a girl who dreams of fame but cannot achieve it. She fails to be accepted into the Italia Conti Academy of Theatre Arts. The verse two says the "wannabe señorita met a group of likely girls [...] but it didn't make her happy", referencing the half-Spanish Halliwell's rise to stardom with the Spice Girls and her subsequent unhappiness with the group. The song's middle-eight references the "Some Girls" situation—"take a look at yourself, get out of the car, it's time to let go—it's gone."
