But it was the Russian tennis star’s relationship with pop star Enrique Iglesias that was the talk of the town.
Ana Ivanovic caused a flutter in tennis circles by announcing her retirement at the age of 29 due to injuries, which had kept her out of action since August and dropped the Serbian to No 63 in the world rankings.
The 41-year-old star, who started dating Kournikova, 35, back in 2001, has always been content and secure about his relationship, with marriage not making a difference, reported E!
online."I don't believe you need a piece of paper to show you love someone," Iglesias said.
Russian Kournikova, who reached No 8 in the world and claimed two doubles Grand Slams alongside Martina Hingis, when injuries cut short her playing career in 2003, quit when she was just 21.
Kournikova, who would often top the charts as the most searched celebrity on search engine Google during her playing career, was perhaps more in the limelight for her relationships.
Within the 15 years of their relationship, they have shared little to no pictures of one another. The former tennis star posted this photo of herself with the Spanish singer and her little brother Allan Kournikova.
