Cee-lo and Danger Mouse are busy working on the follow-up to their 2006 collaboration album St. Elswhere. In a recent interview with Billboard Magazine, Danger Mouse said the album will be ready for the holiday season and is anywhere from “two weeks to two months” away from being completed.

The eclectic pair, who will grace the cover of Billboard’s latest weekly issue, scored a sleeper hit with “Crazy,” which peaked at number 2 on the Billboard Hot 100 Charts and pushed St. Elsewhere past the certified platinum sales mark with 1.3 million copies sold. With the exception of being named “Best Group” at June’s BET Awards, and a handful of tour dates with the Red Hot Chili Peppers, the duo has kept a relatively low profile lately. Nevertheless, as Atlantic Records gears up for its ever-important fourth quarter, Gnarls Barkley is rumored to be the label’s priority during the holiday season.

While no official single has been released, the group posted a message on their website saying an exclusive track will be available on the social networking website Facebook.com, once the site’s Uber Music Player application is launched. “No song is ever done until we have all the material together,” said Danger Mouse. “When we have enough songs to the point where we have an album’s worth, then we’ll go in and start finishing them.”
