Clooney 'will never marry again'

George Clooney's sister doesn't think he will ever marry again.

The 51-year-old actor - who was wed to Talia Balsam from 1989 to 1993 - has been dating former wrestler Stacy Keibler for more than a year but his older sibling Adelia Zeidler believes her brother will always be more committed to his career than his relationships.
