Caroline Wozniacki, the world’s No. 10 tennis player, fueled speculation that she is engaged or even married to No. 1 golfer Rory McIlroy when she was spotted wearing what looked like an engagement ring and wedding band on her left hand when she arrived in Australia for a tennis tournament after the Christmas holiday.

McIlroy accompanied her on the trip. The two were seen together at the Queensland Tennis Centre as Wozniacki practiced for the Brisbane International.

The Daily Mail has the photos of Wozniacki’s two rings:

Wozniacki, 22, denied rumors last month that she and McIlroy, 23, were engaged.

By Friday evening, long after the rumors caused quite a buzz on the Internet, a spokeswoman for Wozniacki denied the rumors once more.
