Arnold Schwarzenegger's son wants to follow in his footsteps and become a movie star.

The bodybuilder turned 'Terminator' actor's eldest son, Patrick, is already a male model, and hopes it will one day lead him to the big screen.

He told WWD: "I've wanted to do some sort of acting stuff down the line. But working as a model is a good way to get comfortable in front of the camera. [Agency] L.A. Models is setting up a lot of cool stuff for me now. Hopefully that will keep jumping."

The 17-year old is already being noticed in Hollywood thanks to a huge image of him being used on a Billboard on Sunset Boulevard advertising Hudson jeans, and Patrick says his mother, Maria Shriver, and father – who are currently divorcing – are very proud.

He added: "They loved it. They support anything I do and I support anything they do. That's how it is."

Meanwhile, Arnold has announced plans to release his autobiography next year. The former Governor of California has reportedly been working on the memoirs for over a year and they may even include details of his recent break up with Maria, after she discovered he fathered a 13-year-old child with their housekeeper, Mildred Patty Baena.

Maria and Arnold also have Katherine, 21, Christina, 19, and 13-year-old Christopher together.
