Novak Djokovic arrived in London a little early this week. The current World No. 1 attended the “Twilight: Breaking Dawn” premier with girlfriend Jelena Ristic. “The vampire fever is on ;)” Djokovic tweeted. The couple walked the red carpet donned in matching all black ensembles.

There has been speculation as to whether or not the ATP World Tour Finals top seed will be up to par after withdrawing from the Paris Masters after a shoulder injury. However, Djokovic also tweeted “things are looking good.”

Things were certainly looking good during Djokovic’s incredible 2011 season. This past year, Djokovic won 3 of 4 Grand Slam titles and 5 of 7 Masters events.

Djokovic will compete in the Barclays ATP World Tour Finals for the 5th time in his career, winning the title once in 2008. He qualified in May following a 41-0 start to the season, making him only the second player to qualify before Roland Garros since 1990.
