George Clooney tops a list of the men in Hollywood who are aging the most gracefully. According to British hair transplant center the Crown Clinic, Clooney, 53, is number one because he often refuses to dye his grey hair.

Second on the list is Clooney's pal Brad Pitt, 50, who tied the knot with Angelina Jolie last weekend. Johnny Depp, 45, made the number three slot.

Rounding out the top five are British actor Daniel Craig, 46, and Austrailian star Hugh Jackman, 45.

The Crown Clinic surveyed 1,000 people and asked them to name Tinseltown's leading 'MAGs' (Men Ageing Gracefully) over age 40.

Crown Clinic surgeon Asim Shahmalak explained, "Clooney is a worthy winner. He has been a global sex symbol for 20 years and he has
just as many female fans now as when he first emerged on ER. He has happily embraced middle age and looks just as sexy as a brooding silver fox as he did as a hunky young doctor in his breakthrough role.
"What is striking about the survey is that every single 'MAG' has a full head of hair. It's a sad fact but nothing ages a man like losing his hair. (This) survey shows that baldness can age a man by as much as 10 years."
