In an interview with B97 in New Orleans before the NFC Championship game, Kris Allen announced that he was going to Haiti to help out with relief efforts. He said he was originally going to do Friday's telethon but got "hooked up" with an opportunity to GO to Haiti instead to help out. (Idol Gives Back, perhaps?)
This kind of humanitarian work is nothing new to Kris. He made many similar trips before he even auditioned for American Idol, traveling to places such as Thailand, South Africa, Morocco (where he got so sick he almost died), Mozambique, Spain and Burma for missionary work. When he was in Thailand visiting a refugee camp, he famously gave up his new, expensive guitar because their guitar was missing pegs, couldn't tune and wasn't compatible with the amps.
