George Clooney says the secret to his success with women is his hair.

The 46-year-old actor - who has been linked to some of the world's most beautiful women including Julia Roberts, Lisa Snowdon and Renee Zellweger - believes a good head of hair is essential to impressing the opposite sex.

Renee Zellweger says pasta is her food vice.

The 'Cold Mountain' actress - who gained 20lbs to star in 'Bridget Jones' Diary' in 2001 - finds it easy to stay away from calorific sweet treats, but insists on including Italian dishes in her diet.

Renee Zellweger doesn't want to have children.

The 'Leatherheads' actress - whose six-month marriage to country singer Kenny Chesney was annulled in December 2005 - has "no ambition" to be a mother, and would rather concentrate on enjoying her independence.

George Clooney loves tormenting the extras on his movies.

The 46-year-old star has revealed he made the minor actors on his 2005 film 'Good Night, and Good Luck' roll in mud for a scene he never intended to use.
