A story that broke US Weekly magazine says that they have gotten to the bottom of the separation of Hollywood couple Ryan Phillippe and Reese Witherspoon. The story says that Phillippe and actress Abbie Cornish had an affair on the set of a movie called ‘Stop Loss.’ They were not very secretive about the affair the reports says as well. Cornish, a 24-year-old Australian, has been seen in films such as ‘A Good Year’, ‘Somersault’, and ‘One Perfect Day.’

The story comes as a shock to Hollywood community as the Witherspoon and Phillippe marriage seemed to be as genuine as they come in tinsel town. The wheels apparently started coming off two weeks ago at the Premier of Phillippe’s new film ‘Flags of Our Father’ when the two were seen fighting and were hostile towards one another. Us Weekly’s Katrina Szish stated on Access Hollywood, “”Reese came across pictures of Ryan and Abbie together and she immediately confronted Ryan. He admitted having an affair. He said all of the rumors were true and said let’s just end this now,”

Phillipe and Witherspoon have two children together ages 7 and 3. They have been together since March of 1997 when the couple met at a party. There has been rumors of fighting before between the couple but have said to have gone to marriage counseling to patch things up. Things are all over now as Witherspoon is enraged that Phillipe has humiliated her. In an ironic twist, Abbie Cornish is very similar in terms of physical characteristics to Witherspoon. Cornish stars along Russell Crowe in the film ‘A Good Year’ which starts next week and Heath Ledger in ‘Candy’ that is a sexual drama. She will have a lot more reporters who want to know her side of the story in all of this. Her office has refused comment.
