Nicole Richie is craving burgers. The reality TV star - who is expecting her second child with partner Joel Madden - often wants the calorific treats in the middle of the night so sends the Good Charlotte rocker out to get her something to eat.

Joel said: "It's not so much the craziness of the craving, it's just when she craves it - it's usually about two or three in the morning and that's on me."
