Rihanna & Jennifer Nettles Perform at 2011 ACMs (VIDEO)

Rihanna's Wildest Outfits
Ri-Ri is a pro when it comes to provocative.
Rihanna has gone country!

The “What’s My Name” songbird took the stage at the 2011 Academy of Country Music Awards on Sunday night to perform with Sugarland singer Jennifer Nettles.

Decked out in a fringed white dress and class red pixie cut, RiRi and a purple pantsuit-wearing Jennifer sang a rousing rendition of the Barbadian singer’s “California King Bed.” Watch the performance after the jump.

Rihanna wasn’t the only surprise non-country act at Sunday night’s awards – American Idol judge Steven Tyler performed with Carrie Underwood using a medley of Aerosmith’s “Walk This Way” and Carrie’s “Undo It.”
