Country fans may not be familiar with pop star Sara Bareilles, but they will likely see a familiar face in the 'Love Song' singer's just-released video for 'Uncharted.' Jennifer Nettles of Sugarland makes a hilarious cameo in the clip, showing off sweet dance moves in her pajamas. (Watch it below.)

Jennifer's home footage appears alongside other musical heavyweights including Adam Levine (of Maroon 5), Josh Groban, Ben Folds, Cary Brothers, Laura Jansen, Pharrell and Ryan Tedder (of OneRepublic). Jennifer first gained notoriety for her impressive comedic timing after Sugarland released their clever video for 'Stuck Like Glue,' which is nominated for Video of the Year at the upcoming ACM Awards.

Find out of Jennifer makes an on-stage appearance with Sara during 'Uncharted,' as Sugarland take their 2011 Incredible Machine tour to more than 60 stops through October.
