The top-ranked tennis player, Novak Djokovic has given birth to his first child, a boy named Stefan. Shortly after the child was delivered on Wednesday Djokovic tweeted that he and his wife, Jelena, were celebrating the birth of their child. “Stefan, our baby angel was born!” Djokovic posted on Twitter early Wednesday. “I’m so proud of my beautiful wife Jelena! Thank you so much for your love and support. We love you all.’’ On his website, Djokovic said “The birth passed in the best way, and the baby and the mother are feeling fine.” RTS, Serbia’s state TV, reported that Djokovic’s wife gave birth on Tuesday in Nice, France, close to where they reside in Monaco. The new parents met in high school, and they have been together for more than eight years. The couple married on 10 July, four days after Djokovic won Wimbledon by beating Roger Federer in the final. Djokovic said on his website that he intends to play at the Paris Masters next week where he will try to defend the title and stave off Federer’s challenge for the year-end No. 1 ranking.
