Which couple is higher profile: Andy Roddick and actress/model Brooklyn Decker or Caroline Wozniacki and Rory McIlroy, golf’s reigning U.S. Open winner? After initially denying they were boyfriend-girlfriend, McIlroy confirmed they were a pair in August. “Why it’s going so well is that we have so much in common,” McIlroy said. “Obviously different sports, but we’re pretty much in the same position at a young age and we can talk about things that probably a lot of 21-, 22-year-olds can’t talk about. It’s nice to have someone that sort of understands what you’re going through.”
