A slew of celebs from Christian Siriano to Sarah Silverman became a part of an apparent viral marketing campaign today when they Tweeted the question "who is sliimy?" Upon further Google, we discovered Sliimy is a quirky French singer who recently released a mellow cover of Britney Spears' "Womanizer." Problem solved!
In other Twitter happenings, a singer contemplated the full moon (as opposed to the "New Moon"), an actor made faces at Roger Ebert, and a band of brothers unleashed their inner plushies.
