The wedding between two-time golf major champion Rory McIlroy and former No. 1 tennis player Caroline Wozniacki is off. Apparently, McIlroy got cold feet—after the wedding invites already went out. “The wedding invitations issued at the weekend made me realize that I wasn’t ready for all that marriage entails,” he said. Their relationship had previously been reported to be on the rocks months ago, but then McIlroy proposed to her on New Year’s Eve in Sydney.
