Miranda Lambert breaks down during Oklahoma benefit concert

Miranda Lambert was overcome with emotion during her performance at the "Healing in the Heartland" concert on Wednesday, which benefited those affected by the tornadoes that struck Oklahoma last week.

The country singer was moved to tears while singing her hit "The House That Built Me," as a tribute to the pets that were lost or displaced during the storms.

Lambert was only halfway through her performance when she had to stop singing for a few moments and regain her composure as the crowd cheered her on.

The benefit was organized by Lamert's husband, Oklahoma native Blake Shelton, who kicked off the evening with a performance of "God Gave Me You," and later sang Michael Buble's "Home" with fellow "The Voice" coach Usher.

Reba McEntire, Vince Gill, Ryan Tedder and Darius Rucker also performed during the concert.

The event, held at the Chesapeake Energy Arena in Oklahoma City and broadcast live on NBC, raised money for the United Way of Central Oklahoma May Tornadoes Relief Fund.
