Is it tennis’ golden couple…Andre Agassi and Steffi Graf?…

 …or is it current Wimbledon Champion, Rafael Nadal?….

 …or former Champion, Martina Navratalova

    …could it be everyone’s favourite…Roger Federrer?

…Maria Sharapova certainly thinks her smile is something to jump up about!

 …or the Williams sisters…who seem to be hiding their smiles!!! 

 …you cannot be serious..it must be John McEnroe!
