Lionel Richie has revealed that his daughter Nicole has made him promise not to date younger women, and insists on 'vetting' his prospective partners.The 61-year-old singer told The Sun that he struggles to recognise women's ages. As a result, he relies on his children to help him decide whether his new girlfriends are suitable.He said: "I find it so hard to distinguish women's ages now. You see a girl walking down the street and Nicole will say, 'Dad! That girl's 18 years old!' and I think, 'No way.'"My children have to vet (my girlfriends) now. Nicole said to me a long while ago, 'Dad I won't date anyone your age if you don't date anyone my age. Deal?'"
