As he has been on so many occasions, Novak Djokovic was the king of the Rod Laver Arena court as the Serbian enjoyed a night rubbing shoulders with the stars at a charity event. 

The world No. 1 bowled over Steve Smith, ran down Peter Bol and swished hoops to showcase his basketball prowess before enjoying a cosy chat with Nick Kyrgios in front of his adoring fans.

But it was a flirty moment with reigning women's champion Aryna Sabalenka that got fans talking. 

Djokovic, a married father of two, mocked Sabalenka's hand gestures while waiting at the net before giving his backside a wiggle in hilarious scenes.

'Wow. What a beautiful view I have,' Sabalenka blushed. 

'Focus Novak, focus,' he said.  

After downing Stefanos Tsitsipas in an exhibition set - a 'rematch' of last year's Open final - Djokovic dazzled a capacity crowd at the charity event and even showcased his wheelchair wizardry to help raise hundreds of thousands of dollars for the Australian Open Foundation.

'I have to pinch myself, honestly, after so many years of professional tennis, coming back to the Rod Laver Arena is always extra special,' the 24-times grand slam champ said ahead of his quest to surpass Aussie legend Margaret Court as the most prolific singles major winner.

'I don't take these evenings for granted ... It's a very special evening.'

Cricket great Smith and Australian Olympic athletics star Bol also joined in the action.

But no one could dethrone the Melbourne Park king.
