Kevin Costner is desperately trying to save his marriage after his wife Christine Baumgartner filed for divorce last week.
The 68-year-old is said to have been "very surprised" by the split, with a friend saying Kevin seems unaware what the reasons are for their divorce.
There has been speculation that Christine gave Kevin an ultimatum before the breakup and is said to have urged him to quit Yellowstone to try and save their marriage.
