George Clooney will never marry, according to his sister

George Clooney's sister is convinced her famous brother will never get married and have children because he is too dedicated to his career.

The Ocean's Eleven star, who is currently romancing former wrestler Stacy Keibler, has been a serial dater since 1993, when he split from his wife of four years, Talia Balsam.

And Clooney's older sibling Adelia Zeidler is convinced the 51 year old won't walk down the aisle again and start a family because he won't want to leave a wife and kids behind while he goes off to make movies.

She tells the New York Daily News, "I would say he probably will not get married... If he was going to get married he would want to be a husband and be somebody who would be there, who would have the time and the ability to focus on the family and the home and all of that. And in the business that he is in, he has to be able to get up and go.

"The majority of actors don't really make their marriages work... If he had children, when he was with them, he would be concerned about his career and if he was working he would be concerned about the children. And he doesn't think it would be fair to split his focus."
