Adam Lambert's 'Acoustic Live!' EP hits in December

adam-lambert-acoustic-cover.jpg Adam Lambert is still just "theorizing" about a second full-length album, but he's giving his fans a holiday gift in the form of an acoustic EP.

Lambert's "Acoustic Live!," a five-song EP of stripped-down tracks recorded mostly during the European leg of his Glam Nation tour, goes on sale Dec. 6. The 2009 "American Idol" runner-up also revealed the cover art for the EP, which you can see up above there.

According to Billboard, the EP will feature acoustic versions of four songs from "For Your Entertainment" -- "Aftermath," "Music Again," "Soaked" and "Whataya Want from Me" -- as well as a version of "Mad World," one of his signature songs from his time on "Idol."
