Celebs love being in the spotlight so much that being on TV, in movies and in our ears isn't enough -- they want to take up your web space too! From Lady Gaga's every day life to Katy Perry's alter ego to that pesky cobra on the loose, find out who made the cut as the biggest Web Sensations of the year!
What hasn't Lady Gaga accomplished on the web this year? Forbes recently named her the Most Powerful Female Tweeter -- beating out Ann Curry, Arianna Huffington and Sarah Palin. In the span of a few months, she made a tumblr dedicated to fashion and took over Farmville and turned it into a Little Monster kingdom called Gagaville in order to promote her album "Born This Way." After landing March's cover of Vogue, she tweeted out a photo of the cover. The notoriously conservative magazine didn't mind too much that the photos were embargoed because the tweets generated so much buzz about the issue.
