Jennifer Nettles

'I Will Always Love You' and '9 to 5' were just a handful of the songs Reba McEntire, Jennier Nettles and Kacey Musgraves sang to celebrate Dolly Parton.

Tonight's (Dec. 1) airing of the fifth annual 'CMA Country Christmas' television special saw Idina Menzel performing an incredible duet with country superstar and host Jennifer Nettles of ‘Let It Go.'

The 'American Idol' finale celebrated the conclusion of its 13th season by inviting big stars onto its stage to perform alongside the former contestants and two finalists. Check out performances by Demi Lovato, Paramore, Phillip Phillips and more.

On tonight's (July 12) episode of 'Duets,' the remaining amateurs performed twice -- once with their superstar and once solo. Jennifer Nettles, who still has two horses in this race, performed 'The Prayer' by Andrea Bocelli and Celine Dion with her "other" amateur partner John Glosson. For his solo song, Glosson tackled 'Bless the Broken Road' by country trio Rascal Flatts.

On tonight's (June 13) episode of 'Duets,' the superstars and amateurs were asked to pick up the pace and sing party songs. Sugarland singer Jennifer Nettles and J. Rome went with Michael Jackson's 'P.Y.T. (Pretty Young Thing') while she and John Glosson did it up on 'Life is a Hightway.'

During their rehearsal, Jennifer Nettles told John Glosson that she really wanted to "focus on his voice this week" (which we think is a good overall plan for any singing competition, really).

It was another hot opening for ‘Duets’ this week with a rock solid duet from Sugarland’s Jennifer Nettles and John Legend. When else will your ears be in the middle of a Nettles and Legend stereo sandwich? That’s what makes ‘Duets’ the singing competition show to watch.

Jennifer Nettles and J Rome once again took the stage on tonight's episode (May 31) of 'Duets' to perform 'You're the One That I Want,' only one of the most recognizable duets known to music fans. The Olivia Newton-John and John Travolta duet from 'Grease' was a "big risk, big reward" moment, since it's a song from a musical that could cheese out ... and quick.
