Nicole Richie craving burgers

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.

"I'm the one that has to run out - either go make her a sandwich or go to In-N-Out Burger or whatever she wants at any given time. It's not unheard of stuff she wants, it's just that when she wants it is inconvenient for me."

Joel – who already has a 19-month-old daughter, Harlow, with Nicole - is looking forward to the new addition to the family, which is due next month.

He said: "We're very, very blessed. We've already had one healthy kid and that's all you can ask for as a parent, healthy kids. This pregnancy is going great."

As well as burgers, Nicole has also been craving chicken pasta.

The 27-year-old wrote on her Twitter page: "I just got fresh made chicken pasta at 12:30am. I'm not one for thank you's, but you know who you are (sic)."
