Katherine’s movie star dad Arnold Schwarzenegger, 73, recently told Yahoo! Entertainment: ‘I’m really proud of my daughters, and Katherine is a winner. And I never, ever thought that my daughter is going to marry an actor.

‘I said to myself she probably will be sick and tired of me dragging her to the sets and always having them watch me blowing up buildings and killing people and stuff.’

The Terminator star added: ‘Now she married an actor, and Chris is a fantastic guy and really easy to get along with and so I’m really happy because he has been such a really wonderful, wonderful husband to her and such a great son-in-law.’
