Shakira: The World Cup has changed my life

Shakira says the World Cup completely changed her life.
The 'She Wolf' singer - who is set to perform at the closing ceremony of the soccer tournament for the third time at the Maracana Stadium in Rio de Janeiro, Brazil tonight - has an 18-month-old son, Milan, with Spanish player Gerard Pique and believes they never would have met if she hadn't signed up to sing the 2010 World Cup anthem 'Waka Waka (Time for Africa).'
