Ana Ivanovic teaches children to be cool
Ana Ivanovic is delivering a message to children in Serbia through UNICEF's "You are cool" campaign.
The tennis star is explaining what makes someone cool:
You are a cool person when you don't gossip about others, and when you accept them and their weaknesses as a part of your society.
The aim of the campaign is to increase tolerance and compassion among children. (via Ana Ivanovic's official website)
