The tennis world number two Novak Djokovic is set to become a father after announcing that he and fiancee Jelena Ristic are expecting their first child.
The six times grand slam champion wrote on his Facebook page: "Jelena and I are truly blessed to soon become parents! My love is pregnant!".
Djokovic, who got engaged to Ristic last September, is set to join Swiss players Roger Federer and Stanislas Wawrinka as the only members of the current world top 10 with children.
Federer, who had twins with wife Mirka in 2009, is expecting a third child in the coming weeks.
Serbian Djokovic is currently recovering from a wrist injury and recently played down fears he could miss the French Open, the only grand slam missing from his collection.
