Madonna speaks out about her sex life with Guy Richie in an interview with Elle Magazine.

She said: "We lie right next to each other with our BlackBerrys under our pillows. It's not unromantic, it's practical.

"I'm sure loads of couples have their BlackBerrys in bed with them.

"I often wake up in the middle of the night and remember that I've forgotten something, so I jump up and make notes."

She said: "I had to marry someone as tough as me. Guy's definitely tough. I had to marry a challenge, otherwise I would just get bored.

"Whatever else Guy is, he's never boring. He can be intolerant of my behaviour but he has certain personality traits which need to change as well."

Her husband, she admits, does urge her to be more feminine. "I've always been very comfortable with my masculine side - the confidence, the ballsiness. I've learnt to be more pliant, more vulnerable and to be comfortable with that."

Madonna revealed she doesn't understand the column inches her marriage generates. "Posh and Becks are much more interesting. Maybe even Camilla and Charles."
