Top Ten Pop Twitter Twats: From Bruno to Britney and Bieber

4. Rihanna @rihanna
Speaking of hot-messes, the Barbadian good-girl-gone-bad is sitting pretty at the fourth spot. It seems 27,950,554 tweeps can't help but stare at her as she throws herself at a dancing asshole and proceeds to get high as fuck. Rihanna, you're shining bright like a diamond on a trainwreck, and we can't look away.



3. Katy Perry @katyperry
Coming in at a solid third place and rounding out the medal stand is the infectiously catchy Katy Perry, who is kind of just like Lady Gaga except a little less weird and definitely not as artsy-fartsy. The California Girl has 31,492,884 tweeters hanging on her every 140 characters, of which she's composed 4,485.
