Here a tweet, there a tweet, everyone's a tweet-tweeting. And even Hollywood's getting in on the fun! From A-listers to Z-listers, celebs are letting it all out on the Internet in 140 characters or less. (Well, at least the ones who don't have ghost Twitterers -- ahem, Britney Spears.) Best of all, there are no publicists to monitor what they're putting out there -- it's unedited celeb craziness! Loves, loves, Love it! See whose tweets we're totally addicted to.
