Move over, Twilight! The Forehead has joined the Twitterverse. Rihanna posted her inaugural Tweet on Tuesday with the uber-brief: “The Wait Is Ova. Nov 23 ’09.”

Super! Does that mean we can expect a new Ri-Ri album as a stocking stocker this holiday season? MTV.com sure thinks so! If Rihanna is releasing a new LP next month, the collection would be the “Umbrella” star’s fourth album, and the follow-up to her 2007 charttopper Good Girl Gone Bad.
