The award, which is named after legendary U.S. comedian Bob Hope, is given out by U.S. military officials to those who give up large amounts of time to perform for and meet servicemen.

"I am so humbled to be in such great company in receipt of this honor from the Department of Defense," Kellie said after accepting the award with her husband Kyle Jacobs, also a musician.

"We've been so blessed to have a great relationship with the USO which has allowed us to be able to take a little piece of home to our service men and women both overseas and here at home," she added.

Kellie has gone on nine United Services Organizations (USO) tours in her career, performing for troops and raising funds for the organization, which helps American soldiers and their families.
