In a move likely to shock tens and tens of people Denise Richards has filed for divorce from Charlie Sheen. She has cited the oft-cited “irreconcilable differences”. The 34-year-old movie star is currently six-months pregnant with the couple’s second child, and their first will be one year old next week. The couple met on the set of the 2000 film ‘Good Advice’, and Richards later did a guest starring role on Sheen’s sitcom ‘Spin City’. The marriage was the second for Sheen and first for Richards.
