Christina Aguilera spices things up in the bedroom by playing doctors and nurses with her husband Jordan Bratman.
She told Maxim: "I like to play doctor. I got Jordan a doctor's outfit with a doctor's bag full of sex toys. I wore the naughty nurse's costume, of course."
She also revealed that she cannot listen to her own music when she is feeling romantic, saying: "I'd be too busy analysing my own voice. I get very nitpicky."
