AMERICAN IDOL: Season 8 winner Kris Allen performs on AMERICAN IDOL, which aired Thursday, Feb. 25 on FOX. CR: Frank Micelotta/ FOX.

Kris Allen was back on American Idol Thursday night – not to be judge, but to rock the house – and to raise a little money in the process.

Proceeds from Allen’s performance of Let it Be on the show will benefit United Nations Foundation’s Haiti relief efforts via the Idol Gives Back Foundation.

The season eight winner actually traveled to Haiti and shared footage from that trip on the show. After the Idol performance Allen reflected on his trip to the region and seeing the toppled city firsthand. However, the spirit of the survivors was inspiring.
