Two months ago Justin Timberlake posted on Instagram announcing that he was spending time in the studio with Little Big Town, so it's no surprise that he sang back up vocals on the bands song "C'mon".

The band's new album Wanderlust was produced by Pharrell Williams and was released digitally today. Pharrell told People "We were in the same studio at the same time, so we had Justin in one room [and] Little Big Town in another room, quite naturally, people are going to visit each other and Justin ended up singing . . . background [vocals] on 'C'mon.'"

Little Big Town brought Pharrell out on the Opry stage to help them perform "C'mon" at the CMA Music Festival kick-off on June 7th.
