The dramatic end of Rory McIlroy and Caroline Wozniacki's relationship is detailed in an explosive new book about the golf superstar. McIlroy, 36, and Wozniacki, 35, started dating in 2011 and got engaged on New Year's Eve in 2013, but they shocked fans when they abruptly announced their wedding was off shortly before they were scheduled to walk down the aisle in 2014. According to golf journalist Alan Shipnuck, McIlroy met his now-wife, Erica Stoll, at the 2012 Ryder Cup when Stoll was working for PGA of America and provided a police escort to his tee because he was running late.
