On Monday, Charlie Sheen reached two million followers on Twitter -- less than one week after launching his account.
"Another record shattered," the actor, 45, Tweeted Monday. "We gobbled the soft target that was 2.0 mil, like a bag of a troll-house zombie chow."
Later, he added, "hey Guinness, might wanna start writing them in pencil, #checkit; you've been warned."
Last week, The Hollywood Reporter reported that Sheen will soon be Tweeting endorsements.
Lady Gaga currently has the most followers -- more than 8.6 million -- followed by Justin Bieber, Britney Spears and President Barack Obama.
Sheen is catching up, though.
Not only is he thriving on Twitter, he is heating up other parts of the web: On Saturday, he hosted a live webcast and attracted more than 100,000 viewers. He showed off a new tattoo on his left wrist that reads "winning."
