BRISBANE, Australia: Tennis star Caroline Wozniacki fuelled speculation she was engaged to golf’s world No. 1 Rory McIlroy on Friday when she appeared wearing a large ring on her left hand.

The blonde Dane, who has been an increasingly cosy item with McIlroy in recent months, was snapped wearing the jewellery on her left ring finger ahead of the Brisbane International.

Australia’s Herald Sun tabloid, which carried separate pictures of Wozniacki wearing the ring at Brisbane airport, noted that the player had denied getting engaged last month.

But the newspaper pondered whether McIlroy had proposed over Christmas, which they spent together, according to pictures they posted on Twitter.

“Is this the photo that proves tennis star Caroline Wozniacki and world No.1 golfer Rory McIlroy are engaged?” the Herald Sun asked.

In November, McIlroy skipped the $7-million WGC-HSBC Champions to watch Wozniacki play tennis in Bulgaria and she then followed him to tournaments in Singapore and Hong Kong.

However, Danish women often wear wedding rings on their right hand and Wozniacki is also known for her penchant for practical jokes.

Earlier this month, she donned padding to mimic Serena Williams at an exhibition event and at the 2011 Australian Open she made up a story about being attacked by a kangaroo.
