Every few weeks we have a marriage, an engagement, a baby or a pregnancy announcement and new relationships seem to be blossoming as well.
A bunch of the new couples are still under the veil of secrecy, like Serena Williams and her coach Patrick Mouratoglou, Maria Sharapova and 21-year-old Bulgarian player Grigor Dimitrov, Victoria Azarenka and Redfoo from LFMAO, Daniela Hantuchova and her mixed doubles partner Fabio Fognini from Italy, but the one romance that we can confirm based on all the kissing photographed on a Melbourne beach is between Ana Ivanovic and Mark Stillitano.
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.
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 Serbian spent 12 weeks as world No 1 in 2008 and won 15 singles titles in her career.
The married mother-of-one posted a photo of her and the star on Instagram and gushed: 'My hero!
This man knows how to do life and be an awesome human doing awesome things.
