World number one Novak Djokovic took to Twitter to announce his engagement to swimwear model girlfriend Jelena Ristic.
Alongside a photo of the happy couple Djokovic, 26, tweeted late Wednesday: "Meet my fiance and future wife :) So happy! Thank you for wonderful wishes #NoleFam and friends"
Ristic, 27, who as well as modelling also runs her future husband's charitable Novak Djokovic Foundation, is a frequent courtside spectator.
Ristic, who lives with Djokovic and their pet poodle Pierre in Monte Carlo, has admitted she finds it impossible to remain detached from the action while her boyfriend is putting himself through yet another gruelling match just yards away from her.
