Pop superstar Madonna sleeps with her mobile phone and so does her husband Guy Ritchie. She says it is not unromantic.

Thesun.co.uk reports her saying that she places her BlackBerry under her pillow.

She said, "We lie right next to each other with our BlackBerrys under our pillows. It is 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."

"Guy's always waiting for me to come to bed, so he plays Brick on his Blackberry until I'm ready," she added.
