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.

The two tennis stars posted pictures of themselves with Joe Jonas and model Gigi Hadid. Fellow clubgoers at VIP Room said Williams' group of nearly 30 ordered Champagne and vodka and danced until early Monday morning.

GMA had teased Williams' appearance on Monday morning, then, less than an hour later, had to tell viewers she wasn't going to appear. Today had also confirmed that the champ was booked, and they had announced her appearance at the top of the show, before she canceled.

It was also revealed that while Williams, who withdrew from Wimbledon earlier this summer after a viral illness left her disoriented, had been out late, her team, including her agent and publicist, decided that she was too tired to do a round of TV shows on a few hours' sleep after two weeks of intense competition.

The American was seen out again Monday night with Wozniacki at a dinner for Miami Heat star Chris Bosh's new tie line, Nice Tie, at Sons of Essex, the report added.
