Blake Shelton is one of the biggest names in country music, and thanks to his coaching position on NBC's 'The Voice,' the star has become a household name all across America. Even fellow coach Usher loves him, which he made evident by covering one of Shelton's hits recently.

Together, Shelton and Usher headlined the United Way of Metropolitan Dallas' 90th Birthday Bash on Feb. 6. The event was held at AT&T Stadium and included special guest First Lady Laura Bush. During the evening, among his own hits, Usher performed Shelton's 'Neon Light.' His version was smooth and soulful, the perfect counterpart to Shelton's more country, twangy version.

"How'd I do?" a smiling Usher asked the audience after his delivery.

"It doesn't matter if it’s country or R&B music -- an emotion is an emotion, right?" the iconic pop-R&B star remarked later.

Usher and Shelton also did duets of 'I Get by With a Little Help From My Friends' and Shelton's 'Home' for the crowd.
