Nicole Richie is addicted to sending sexy text messages to longtime boyfriend Joel Madden.

In an interview with Star Magazine, a tattling former bodyguard of the pint-sized socialite claims Nicole loves sending x-rated texts of her sexual fantasies to the Good Charlotte rocker, with whom she has a 10-month-old daughter, Harlow.

“She is a pistol who says exactly what is on her mind,” says the handler. “When she is not with Joel, she is constantly sending sexy text messages, telling him what she is wearing and what she wants to do with him when she gets home.”
