Ana and Victoria Azarenka enjoyed a light hitting session on the roof of the Villa Miami hotel in Rome at the weekend. The informal exchange took place on a custom-made, mini-tennis court with St Peter's Church as a backdrop.
The event, which was arranged by WTA title sponsors Sony Ericsson, is the latest in a long line of spectacular stunts Ana has taken part in to help promote the sport.
During the Sony Ericsson Championships in Doha last year she played against Elena Dementieva on a desert island, while three years ago she was featured in a Sony Ericsson commercial that included her jumping across skyscrapers while rallying with Daniela Hantuchova.
"Sony Ericsson always comes up with fun and different things for us to do to promote our sport and this villa was a beautiful location. I love Rome and the city looks amazing from up here. I hope the weather stays as good as this all week!"
Ana faces home favourite Francesca Schiavone in the second round of the Internazionali BNL d'Italia on Tuesday. Click here for live point-by-point scoring from the Foro Italico
