Former Australian Olympic swimmer Stephanie Rice has faced the brunt of social media over the years and she recently admitted that she's learnt from her mistakes. Back in 2010, Rice made headlines when she sent a homophobic tweet to the South African rugby union team.

After the Springboks were defeated by Australia, she tweeted: "Suck on that, f****ts." She later apologised for the tweet, but lost an endorsement deal with luxury car manufacturer, Jaguar.
