Today on Twitter, Katy Perry found her way to a carnival, where she rode rides, ate corn on the cob and ran into Justin Bieber, of all people. The ‘Teenage Dream’ hitmaker tweeted a photo of herself in a cowboy hat and pearl-snap shirt, standing next to a dreamalicious, larger-than-life spray paint version of the Biebs. His response? “That dude has gorgeous locks but whats with the teeth?!?” We think the big photo is a pretty good doppleganger, thanks to some multi-talented carnies. The real ‘Baby’ singer also hit up his fellow teen icon, Taylor Swift, with a tweet inviting himself to one of her shows. See what your fave celebs were tweeting today!
