One Direction hottie Harry Styles reveals that he has a limit to his love -- no higher than his mother's age! The young singer has been involved with an older woman before -- he dated 32-year-old "Xtra Factor" host Caroline Flack. The singer was only 17 at the time, which made their relationship even more taboo. But that's not the only older lady the teen's been involved with! This summer, reports surfaced that he'd had an affair with radio DJ Lucy Horobin -- who is not only 14 years his senior but also married! Harry doesn't seem to care about age, but maybe in the future he should pay more attention to whether his conquests are single or not.
