Another Hollywood Marriage Kaput: Richards and Sheen Divorcing

This is surprising news (even for Hollywood) considering Denise Richards is six months pregnant with their second child. They also have a year-old daughter, Sam.

Richards first met the now 39-year-old Charlie Sheen while shooting an independent film "Good Advice" in 2000, but the two didn't start dating until 2002 when Richards guest-starred on Sheen's series, "Spin City." They were married in June that year and co-starred in "Scary Movie 3" together.

Sheen is well-known for his roles in "Ferris Bueller's Day Off", "Platoon" and "Hot Shots". Sheen was infamous for partying hard and being with a string of women until he started dating Richards. He now stars in the CBS sitcom "Two and a Half Men".

Richard cited "irreconcilable differences" in the court papers filed on Wednesday.This is her first marriage, Sheen's second.
