has found his love match.
The world's no. 1 ranked tennis player is going to marry his high-school sweetheart, Jelena Ristic.
"We're engaged!!! Getting used to introducing Jelena as my fiancée and future wife," Djokovic, 26, wrote Wednesday on Instagram
and posted a photo of Ristic kissing him on the cheek. "Couldn't be happier."
According to reports, the Serbian champion proposed to his girlfriend of eight years over the weekend in Monte Carlo, where he currently lives. The couple first met in high school in Belgrade and have been together ever since.
Ristic, a former swimwear model, earned a master's degree in management from Milan's Bocconi University. She spends most of her time cheering on her six-time Grand Slam champion beau on tour and runs the Novak Djokovic Foundation, which benefits underprivileged children in their home country.
The newly engaged pair, known as the "Will
of Serbia," plan to get married next year.
