Alicia Keys only requests a packet of chocolates in her tour rider.
The 'Doesn't Mean Anything' singer - who has won nine Grammy Awards during her career - is an undemanding star and is happy if a packet of M&Ms are waiting for her to eat after she comes off stage.
A source said: "All she asks for is bags of M&Ms. She doesn't even ask for a bowl of them, or for any particular colour to be picked out."
The 29-year-old star - who has sold over 30 million albums worldwide - is unlike many of her fellow musicians who are known for their outrageous backstage requests.
Mariah Carey lives up to her diva reputation by demanding £750-a-bottle Cristal champagne and Evian water, with 50 Cent following suit with an 18-page rider which includes details on how his food should be served to him on finest china plates.
Lady GaGa requests tea, cheese and a pot of honey - which soothes sore throats and helps singers keep their vocal cords in top shape.
