Celebrity Tweets: Jonah Hill, Lauren Conrad, Megan Gale

There were two things that had our favourite famous Tweeters up in arms this week: The supposed Mayan apocalypse, and the proposed changes to everyone's favourite app, Instagram. And yep, as we've come to expect, the celebs we follow were vocal about both. Pink went as far as to say she'd be quitting the photo-sharing app for good, while Jonah Hill likened the effect of the new rules to a broken heart (what a romantic). As for the end of the world? Some people were relieved to see it was nothing more than a myth, while others (like Lauren Conrad) were kind of relying on the end to be nigh. And Megan Gale? She just wants us to have a safe Christmas break — proving she's gorgeous on the inside, too.
