Sugarland's Jennifer Nettles will have an unconventional duet partner at the ACM Awards on April 3 in the form of pop diva Rihanna! Let's hope Kristian Bush doesn't get jealous. 

RyanSeacrest.com exclusively revealed that Rihanna will be performing her new song, 'California King Bed,' with Nettles. It's official: Rihanna is going country, if only for one night! The song appears on Rihanna's fifth album, 'Loud,' and we are looking forward to seeing the two vocal powerhouses play off one another during this must-see performance.

The ACMs are set to air live on April 3 at 8 PM ET on CBS. The star-studded event will be held at the MGM Grand in Las Vegas, and will include performances by everyone who's anyone in country music, from Toby Keith to Keith Urban. It truly is one of the biggest nights in country music.

In other Sugarland live performance news, the band will perform on tonight's much anticipated results episode of 'American Idol.' Perhaps Nettles and Bush can offer some friendly advice to this season’s country contestant Scotty McCreery!
