    Age difference: 32 years

    Joan Collins made headlines when she began a romance with then 35-year-old theatre company manager Percy Gibson and one of the questions the couple constantly faced was that of their three-decade age gap. "I'm not going to be so nave as to pretend we didn't spend a lot of time discussing that very issue," Percy told HELLO!. "But it's a damn shame for two people so happy together to make the difference in age the reason for not being together." And his glamorous wife agrees. "I've always felt age shouldn't be a chronological issue," she told us. "I know that I look and act a lot younger than I am." Besides, she adds: "I'm much more secure in myself than many girls in their 20s."
