Miranda Lambert put her heart into the Healing in the Heartland concert Wednesday night, breaking down during her performance of "The House That Built Me." Her song was a tribute to the pets who were lost during the tornado in Moore, OK, last week. Miranda, as well as Reba McEntire, Vince Gill, Ryan Tedder, and Darius Rucker, performed at the benefit concert that was organized by Blake Shelton, Miranda's husband and an Oklahoma native. Proceeds went to the United Way of Central Oklahoma's May Tornadoes Relief Fund. Watch her performance.
