Rumours of a romance between Ana Ivanovic and Bastian Schweinsteiger have been rife for quite some time, and those rumours have been fueled in light of the footballer's very boyfriend-like actions.
The duo have the potential to be a power couple in the world of sport, and it looks as though they will.
It takes some dedication to fly halfway around the world to watch somebody practising the sport they do for a living, but that is exactly what Schweinsteiger has done. Those are hardly the actions of friends-only!
Ivanovic is busy in her preparations for the 2015 season and January's Australian Open in Melbourne, she used the city to have a session which was apparently watched by the Bayern Munich star.
The news came to light after a Twitter user spotted the pair and uploaded his evidence.

After months of infrequent, yet friendly public appearances together, surely it's only a matter of time before they go official. Schweinsteiger could even join the likes of Grigor Dimitrov, Kim Sears and Mirka Federer in the players' boxes; all famous spouses who cheer on their partners at the big tournaments.
Their first romantic links came back in the summer when the Ice Bucket Challenge was all the rage with the top celebrities. In Ivanovic's, she nominated fellow tennis giants Roger Federer, Serena Williams and also Schweinsteiger, slightly out of the blue.
Since that time, they have been spotted together in both New York, following the US Open in September, and Ivanovic's home city of Belgrade in October while Schweinsteiger was sidelined with injury.
The German, who won the World Cup in Brazil in summer 2014, is now back in action, but had the time to watch his potential Serbian lover courtesy of a winter break in the Bundesliga.
Ivanovic will be hoping Schweinsteiger's winning mentality will rub-off on her whilst he's watching the training sessions; she still only has one Grand Slam title to her name, and that was won way back in 2008.
Her only final appearance in a major away from the French Open came at Melbourne almost seven years ago. The former world no.1, however, was denied by Maria Sharapova - a pairing which isn't quite as nice.
Ivanovic and Sharapova are more reminiscent of Rory McIlroy and Caroline Wozniacki's current feelings towards each other. The top tennis stars had some timing related argy-bargy earlier in the year. Another meeting between them in a final this year would be fairly tasty.
