Today’s Best Tweets: Greyson Chance Gets Bitten By a Fan, ‘Twilight’ Style

The same week that the new 'Twilight: Breaking Dawn' movie hit theaters, two pop stars were bitten by fans. While we don't suspect it's an outbreak of vampire wannabes, it is an unfortunate coincidence. 'Unfriend You' hitmaker Greyson Chance visited eager overseas fans today, one of which decided to sink their teeth into the young singer. Don't worry, he lived to tweet the tale, but the full-on mouth attack comes just days after a fan tried to take a chunk out of Britney Spears' leg while she straddled his head (okay, maybe that one was her fault).

Also on Twitter, Swizz Beatz shared an aww-dorable photo of his daughter enjoying Disney, while Drake's 'Trust Issues' surfaced and Nicki Minaj pimped the 2011 American Music Awards, which air Sunday on ABC.
