Caroline Wozniacki and Rory McIlroy are rumored to have taken their relationship a step further by getting engaged. The pair flew into Brisbane, Australia, bright and early on Friday morning, Caroline flashing what appeared to be a diamond engagement ring on her left hand.

The talk of wedding bells is increasing after the couple allegedly purchased a Florida mansion together earlier this month. Some say the couple are already secretly married, alluding to the fact that she has also been seen wearing a diamond and sapphire band. Caroline has spoken of Rory’s never-say-die attitude as being an inspiration to her. But she will not be receiving any coaching tips while Rory accompanies her in Brisbane, before he flies to Dubai for the year-opening Abu Dhabi Championship.

” He leaves me alone to just let me do my thing.”

Rory is sure Caroline’s rankings slide and failure in Grand Slam events has nothing to do with her work ethic.

” Seeing how hard she works and how hard she practices and how dedicated she is, it definitely flipped a switch with me that I could be a little more like that. ‘She’s definitely been a great influence on me.”

Ex World number one Caroline, now ranked 10 is one of eight top-10 players in the main draw in the Australian Open in Brisbane, where Serena Williams, Maria Sharapova, Victoria Azarenka and Samantha Stosur share top billing. She is fully aware of the strong competition in this tournament;

”It is tough but that’s how I want to start the year, I want to start off well and this field gives the perfect preparation. Obviously I want to go far here and, to do that, I have to play against the best.”
