Celebrity Tweets: Jaime King, Pink, Ellen, Ricky Gervais

Nothing gets people onto social media quite like a huge event, and today has been the perfect example. After news of the horrific shooting in Connecticut broke this morning, every celebrity you can think of took to Twitter to express their grief. Stars like Jaime King, Pink, Giuliana Rancic and many more shared their thoughts and sadness on the social networking site. It wasn't all sad, though — Twitter is also a place for celebrities to try their hand at comedy, to inspire, to share news (a surprise wedding, for example!) and to clear up any rumours (thanks, Olivia Wilde). There's the funny (Alexa Chung), the offensively funny (Joan Rivers — who else?) and so much more! Click through to catch up on this week's celeb Twitter happenings.
