Guo Jingjing and Kenneth Fok Kai-kong The couple welcome their first child into the world - a boy. "The son of myself and Jingjing was born this morning, weighing 3.3kg. Both mother and child are well and healthy," Fok, 33, wrote in a microblog. "The smooth arrival of this little life makes us feel very happy, and fills our family with incomparable joy." The child was born at the Hong Kong Sanatorium and Hospital. Guo, 31, shares the world record for the most Olympic medals won by a woman diver - six. The couple dated for seven years before marrying last November. It was one of the city's most extravagant weddings and cost HK$15 million. Madonna The pop diva is the world's top-earning celebrity, according to a Forbes magazine list, raking in US$125 million in the past year. The Material Girl's money came mainly from her US$305 million-grossing MDNA tour, but was helped by sales of her clothing and fragrance brands and various investments. Madonna's top spot compares with her previous peak of US$110 million in 2009, but falls short of the US$165 million raked in by Oprah Winfrey in 2008. Lleyton Hewitt The Australian tennis veteran rolled back the years when he sensationally dumped Argentine No6 seed Juan Martin Del Potro out of the US Open in the second round. At 32, Hewitt reserves his best form for the big occasions these days, and he edged Del Potro - like Hewitt, a former US Open champion but eight years his junior - in an epic five-set battle at the Arthur Ashe Stadium.
