As you may have noticed, Charlie Sheen just set a new Guinness World Record for being the fastest person ever to reach 1 million Twitter followers. (He accomplished that mean feat in 25 hours and 17 minutes between Tuesday and Wednesday this week.) But he's not just on Twitter for kicks—or to impress more people with the ramblings of his newly enlightened self. He's on it to make money by endorsing products. As GQ reports, Sheen's handlers reached out to Los Angeles-based digital company ad.ly, which set up his Twitter account. Ad.ly specializes in marketing partnerships with celebs, getting folks like Snoop Dogg and Kim Kardashian (and now Sheen) to recommend products and services in exchange for cash (in Kim's case, supposedly $10,000 per tweet). Sheen confirms to TMZ that it's all about the money. ("I'm unemployed!" he points out.) He has yet to make an overt pitch through the account (unless Tigerblood is his forthcoming soft drink), and it remains to be seen whose products he'll endorse. Presumably he will start by peddling his own fragrance. UPDATE: More details here from Brian Morrissey. "We want to be top of mind if they think about monetizing it," says ad.ly CEO Arnie Gullov-Singh. "He may never think of monetizing it."
