For both Charlie Sheen and Twitter, 2011 was the year of the tiger (blood).
Both Sheen and the stuff he says runs through his veins made Twitter's list of hot topics for 2011. Sheen, who had a busy year after being fired from Two and a Half Men, is listed as the No. 1 most talked about actor, followed by Macaulay Culkin, Ryan Dunn and Ricky Gervais. His Two and a Half Men replacement, Ashton Kutcher, also made the top 10, landing at No. 8. (#tigerblood is listed as the second most talked about hashtag of the year.)
Two and a Half Men itself was the second most talked about TV topic behind No. 1 ranked Pretty Little Liars. Rounding out the top 5 for television are The Craigslist Killer, Golden Globe Awards and People's Choice Awards.
Elizabeth Taylor, who passed away in March, topped the most-discussed actresses list. Among the others in the top 10 were Black Swancastmates Mila Kunis and Natalie Portman, along with Harry Potter's Emma Watson and The Vampire Diaries' Nina Dobrev.
Despite gaining notoriety as one of the worst songs of the year, Rebecca Black and her tune "Friday" landed at the top of the music list, followed by the likes of Nate Dogg, Gerry Rafferty and Gil Scott-Heron.
Are you surprised by the topics that made the list?
