Jessica Simpson suffers stressful bouts of insomnia - and is only able to sleep at night if she lies on the floor. The actress/singer often has to leave American footballer beau Tony Romo slumbering in their shared bed, while she takes to the bedroom floor in a bid to get some rest. Simpson reveals, "It's a mental thing. If I tell myself I can't fall asleep, there's no way I can so if I end up lying on the floor I do."
