In 2011, Sheen made the headlines for a series of public rant. Her comment, "My fangs are dripping tiger blood," culminated with the comment to online celebrity gossip site RadarOnline.

Former Egypt President Hosni Mubarak's resignation hold the top position in the news list which was followed by the US special forces' raid on Osama Bin Laden's hideout in Pakistan. Japanese earthquake holds the third position.
"More than anything, these trends demonstrate how Twitter connects people with common interests. Instead of watching the news at home alone, we watched them together on Twitter," Twitter claimed in its official blog.
