Andrea is the leader of the Emos in the first film. She has black hair with coloured streaks and various body piercings. Andrea is quite morbid, as shown in her conversation with Flash during a 'Crime' lesson: Andrea objects to being called a 'goth', even though she shares many personality traits with goths. She hates the chav Taylor, although they develop tolerance towards each other as the film progresses. Andrea is involved in stealing the 'Girl with a Pearl Earring' painting, along with Kelly and Taylor. She has the job of actually taking the painting, performing a dance over security lasers that Kelly oversees. During the Heist it is reavealed that Andrea is afraid of heights, but she conquers this fear to take a zipwire above the set of 'School Challenge'.

Andrea is portrayed by Paloma Faith.
