Nicole Richie is launching a campaign to save America’s lampposts from dog pee.

The Simple Life star is promoting Swedish inventor Lennart Jarlerbro’s dog urinals which are tied to street lights, preventing them from being eroded by the animals’ urine.

Nicole – who is expecting her first child in January – said: ‘This invention is just so clever. It’s a cute rubber cup attached to the post and a hose that pipes urine into the gutter.’

Jarlerbro, who revealed his designs earlier this month, came up with the idea after getting annoyed at seeing lampposts prematurely corroded.

He said: ‘The average lamppost has a lifespan of 30 years but my invention could add a further 15 years.’

Meanwhile, Nicole and her fiancé Joel Madden have started their own children’s charity.

The 26-year-old star and the Good Charlotte frontman have set up the Richie Madden Children’s Foundation for mothers in need. Next month, the charity is set to donate 100 ‘Mom-to-Be kits’ to the Los Angeles Free Clinic.
