Well now we know why John Mayer and Jessica Simpson lasted so long. Jessica has confessed that she loves the way the Pussycat Dolls dance. But will never attempt to do them in public. Instead, she reserves them for the bedroom.“I love the way they dance,” she said. “I do some of the moves myself but not in public - I keep that for the bedroom.” She added: “I love watching them. I take notes and then keep them for those private moments.”
