Although they used the language of divorce, the duo added: "Our sincere hope is to have new music for you in 2013." With backgrounds in gospel and rock, the duo found unexpected success with their 2011 debut album, Barton Hollow. - AP

A star of the recently released movie Wreck-It Ralph, McBrayer said he's eager to see what roles the future might hold. "I know how good I got it right now, but then you do always wonder - what if I would be the best serial killer in the world or something? So I'm open for anything. Old boy just wants to work." - AP
