The Year in Arrests: 2011
Dec 22 -- Adam Lambert was arrested in Helsinki, Finland after he and his reality star boyfriend Sauli Koskinen got into a brawl outside a gay bar.

Adam Lambert will return to the "American Idol" stage next week, as the season 8 runner-up will perform an acoustic version of his song "Aftermath" during the results show next Thursday (Mar. 10).

Following the performance, a new remix of "Aftermath," courtesy of pop producer Billboard, will become available on Lambert's official website.

"Billboard turns the song into a fresh new dance pop anthem to blast on the radio and in the clubs!" Lambert says of the producer, who co-produced Britney Spears' "Hold It Against Me." Part of the song's proceeds will support crisis intervention organization, the Trevor Project.

The acoustic performance on Thursday's episode will likely strike a different chord than Lambert's official return to "Idol" last season, which was highlighted by an epic, laser-soaked performance of "Whataya Want From Me." The singer's appearance on the show next week follows the announcement that another "Idol" alum, season 7 winner David Cook, has recorded a cover of the Simple Minds' "Don't You (Forget About Me)" that will be used as the official "Idol" season 10 exit song beginning next week.

"Aftermath" was featured on Lambert's 2009 debut, "For Your Entertainment," which has sold 801,000 copies, according to Nielsen SoundScan. "Whataya Want From Me" was nominated for Best Male Pop Vocal Performance at the 2011 Grammy Awards, but lost out to Bruno Mars' "Just The Way You Are."
