According to Newsweek magazine, Schwarzenegger told his neighbour: "I think things will work out OK with Maria, but if they don't, I'm getting me a 20-year-old honey."
The 'Expendables 2' star is said to have told his wife of 25 years to leave their Californian mansion, which forced her to live in a hotel while Arnold remained in the property, and when she asked for a divorce he insisted that he would be the one who still has friends when they separate.
He said: "I have the money, the power, and the plane, and I will have the friends."
According to the publication, the 'Expendables 2' star "could not understand" why Maria - who has four children with the actor - didn't forgive him.
The piece states: "Arnold is a very different kind of person [to Maria]. Anything that posed emotional pain or difficulty, he was out of there.
"He could not understand why Maria could not just forgive and get on with things, and when Maria said she needed a trial separation and told Arnold to move out, family and friends say that he refused. It was his house, and he wasn't budging..."
