Both at the top of their game, sparks first flew after their meeting at a boxing match in 2011 and the world was soon talking about the powerhouse sporting couple that were Rory McIlroy and Caroline Wozniacki.
Shortly after ending his relationship with his childhood sweetheart Holly Sweeney, the Irish golf star was spotted on a string of dates with the blonde Danish player.
The former tennis world number one was impressed after meeting the ex-US Openchampion in July 2011 and public flirting between the pair on Twitter quickly followed.
In August, the Down native confirmed that he was dating Caroline, then at the top of her game as world number one, saying their understanding of each other’s pressurised careers brought them close together.
Despite initially shying away from the limelight, a steady stream of PDA’s soon followed as the pair were snapped out and about as well as supporting one another at their respective sporting events and the couple were soon dubbed Wozilroy’.
Even as their careers hit low points, the couple insisted that they were as strong as ever.
During their three-year relationship, Rory stepped onto the tennis court, jokingly taking over during a match and Caroline was often spotted cheering on Rory on the golf course with his parents.
However, after two years of being touted as love’s young dream, the busy pair were snapped together less and less, fuelling speculation that behind the scenes things weren’t so picture-perfect.
Rory and Caroline found themselves constantly dismissing rumours of a split, which began last summer and climaxed in October 2013 after she posted an unflattering picture of him asleep wearing his glasses.
But the pair kissed and made up a short time later and the 24-year-old golfer popped the question with a giant sparkler last December.
He got down on bended knee after the New Year’s Eve fireworks show in Sydney and presented her with an eight-carat engagement ring worth an estimated €150,000.
They have been regularly photographed ever since, with Caroline playing the part of a devoted girlfriend by caddying for him during the recent Masters in Augusta.
Only three days ago they were dining in one of the most expensive restaurants in the world together - Nobu restaurant in Monte Carlo over looking the French Riviera.
But, it now appears this could have been a last romantic outing for the young couple.
