Australian media reported Friday that Caroline Wozniacki arrived to play at the Brisbane International with a diamond ring on her left ring finger, sparking speculation that she and boyfriend Rory McIlroy had become engaged.
The Australian Associated Press and other media outlets said Wozniacki wore the ring at the airport and as she prepared for her afternoon practice session at the Queensland Tennis Centre but removed it to play on court.
McIlroy, the world's No. 1 golfer, accompanied Wozniacki on her trip Down Under.
The Brisbane International begins Sunday with Wozniacki's first match in a tournament that includes Serena Willliams and Maria Sharapova, if fit.
