Ever since Charlie Sheen gave the explosive radio interview that led to the cancellation of his hit CBS show, Two and a Half Men, the tiger-blooded warlock--his words, not ours--has primarily communicated with America through the media. But the filter's been removed. At around 5 p.m. on Tuesday, Charlie Sheen joined Twitter, and his meteoric rise on the popular micro-blogging site has stunned even the most prolific tweeters.

"I've been hanging around Twitter for a long time and I can't remember someone taking off quite this fast," marveled The Atlantic's Alexis Madrigal, who graphed Sheen's follower count for his first hour on Twitter. "The man's over 100,000 followers without having tweeted a single time." Sheen has since tweeted (twelve times to be exact), created a hashtag, #tigerblood," that has become a worldwide trending topic, and attracted over 800,000 followers. Calling himself an "unemployed winner" in his Twitter bio, Sheen devoted his inaugural tweet to a photo of him and Bree Olson--one of his "goddesses"--holding bottles of chocolate milk and pineapple juice over the caption "Choose your Vice."

But while Sheen is racking up Twitter followers by the second, he's only chosen to follow 16 people. Who are the lucky few--the kindred spirits he can turn to, at least digitally, as the controversy surrounding him mounts? It's a motley crew:

Rick Calamaro: Sheen's assistant

Fred Durst: The frontman for the band Limp Bizkit endorsed Sheen's account in a characteristically emphatic tweet: "All of you do me, and yourself, a favor and follow @charliesheen and @rickcalamaro -no joke. It's time to WIN! let me hear you say BRING IT!"

Nick Swisher: New York Yankees outfielder

Brian Wilson: The black-bearded San Francisco Giants closer also knows a thing or two about how to do a colorful interview

Floyd Mayweather: The professional boxer's informed us that "Me & @charliesheen are always "Winning" (I'm 41-0)" and that "I really like @CharlieSheen in "The Chase"... sex while driving is unbelievable."

Piers Morgan: The CNN host says he's the reason Sheen joined Twitter in the first place. Morgan tweeted that he told Sheen to sign up for the social networking site during an interview earlier in the week. "Sheen chuckled and said: 'That could be fun, maybe I will,'" Morgan says. He's crowned Sheen the "New King of Twitter."

Howard Stern: The radio host recently interviewed Sheen on his show and, in an appearance on the Daily Show, asked Jon Steward, "Who is more insane, Charlie Sheen or Glenn Beck?”

Sean "P. Diddy" Combs: The rapper's been known to court controversy himself , which may explain why he tweeted, "@charliesheen can u please send me the address to ur house? Ive been dreamin about a party like this all my life #winning! See u soon! Lol."

Alyssa Milano: The actress famous for her roles on Who's the Boss, Melrose Place, and Charmed has so far remained mum on all things Charlie Sheen, at least on Twitter
