Demi Lovato tweeted that she was a bad driver which leaves us wondering if she perhaps got into a fender bender recently? Adam Levine got literary with a Mark Twain quote and John Legend had some unfortunate news for his followers, specifically those in South Africa. Coldplay posted a picture of some Mylo Xyloto cupcakes and Bow Wow tweeted a picture of he and Birdman on his 'Sweat' video shoot. Read what your favorite stars were chirping about today!
