New York: World number one Serena Williams missed all of her TV appearances after winning the US Open championship as she was parting until the early hours of Monday with Caroline Wozniacki.

Williams was due to appear on NBC's ''Today'' and ABC's ''Good Morning America'' followed by ''Live With Kelly and Michael'' with her trophy on Monday after bagging her 18th Grand Slam title. But the superstar canceled her appearances because she was too tired after she celebrated with her friend and final opponent Wozniacki, who has become close to Williams following her split with golfer Rory McIlroy, at Tao and VIP Room, New York Post reported.
