Novak Djokovic has announced via Twitter that he is to become a father for the first time.
The 26-year-old tweeted his delight to just under three million followers with a picture of fiancee Jelena Ristic and a message which read: "Jelena is pregnant!!! We will be parents soon! #blessed"
The happy couple have been together over nine years and announced their engagement in September. The due date of the child is unknown.
Djokovic's rivals will certainly be hoping that the world no.2 suffers plenty of sleepless nights tending to a screaming newborn baby.
This news caps off a great week for the Serbian star. There had been doubts over Djokovic's potential participation in the French Open, and even Wimbledon, but he should be fit to return in a couple of weeks.
Djokovic admitted his concerns after failing to retain his Monte Carlo Masters last week, courtesy of a semi-final defeat to eventual runner-up Roger Federer in which his arm was heavily bandaged.
However, after visiting a specialist, he received the all-clear: "Fortunately, the situation with the injury is better than it first seemed," he said this week.
"Doctors assured me that I will be ready for Madrid, then Rome and Roland Garros, just as it has been planned.
"However, I need to continue with the recovery process and full medical treatments. It means I will have to take a short break in order to recover as soon as possible."
Djokovic had been in imperious form before Monte Carlo and Federer ended a 15-match winning streak.
Victories on the hard American courts of Indian Wells and Miami meant that the world no.2 was on course for a third successive Masters 1000 tournament triumph but his problem cut short that run.
Buoyed by his impending fatherhood and good injury news, Djokovic could finally be ready to win this year's French Open and complete a Career Slam in the process. Roland Garros is the only Slam that the right-hander has failed to win.
Djokovic has tasted success in six finals. Four of those have came in the Australian Open. While in 2011 he stormed to Wimbledon and US Open titles, his only successes at those events.
This season could provide challengers with their best chances to break Rafael Nadal's dominance in Paris. The world no.1 has only ever lost once on the French clay and that was back in 2009, he's picked up a record eight titles - beating Djokovic in the final once, back in 2012.
The 'King of Clay' as he is known, however, appears to be struggling for form this season. A shock quarter-final loss to David Ferrer in the principality, where he also has eight trophies, compounded a fall at the last hurdle against his Serbian rival at Miami.
The world's best two players currenlty in world tennis have struck up a fierce rivalry which the Spaniard edges in their head-to-head battle but the Serb star has won their last three meetings.
