Nicole Richie is lending her name to a bizarre U.S. campaign to save street lights - from the dangers of dog urine. The star, who has two dogs - Foxxy Brown and Honeychild - has signed up to promote Swedish inventor Lennart Jarrelbro's latest creation, dog urinals, to stop the metal on the posts being eroded by the chemicals found in canine waste products.

She says, "They're so clever. It's a cute rubber cup attached to the post and a hose to pipe the urine into the gutter."
