GEORGE CLOONEY isn’t concerned with how his looks are changing with age. ‘Gravity’ star George Clooney doesn’t mind that his hair is going “grey” and joked he doesn’t “have to worry” about his looks because he was never likely to be “an action star”.The 52-year-old actor is proud his hair is going “grey”, insisting he would never dye it, and said not being an “action star” means he doesn’t “worry” about his image too much. Speaking to the Daily Express newspaper, he said: “Luckily it became obvious pretty early on that I was not destined to be an action star so I don’t have to worry so much about how I look. “I hear all this talk about how grey I am getting but I can’t imagine ever dying my hair. “My dad had this full head of white hair and I think it looks pretty good.” The ‘Gravity’ star - who split from his girlfriend Stacy Keibler last summer - also insisted he will “never” remarry or raise a family, and he wishes people would “believe” him. He added: “This fascination with my love life is really something. I keep saying I’ll never get married again or have children but people just don’t want to believe me.” Now, he has happy to be living with his pet dog Einstein - a black cocker spaniel - and he doesn’t let his critics get to him. He said: “I love my life as it is. I realise whatever worries I have are trivial in comparison to those of many people. “I have learned not to be swayed by the attention. It doesn’t matter what people I don’t know have to say about me. “What matters is what my friends and family think of me and so far they are all returning my calls.”
