Yep! im as shocked as you are but this just came in from her fan twitter account "RihhanaDaily". it read
"New: Rihanna to perform "California King Bed" at Academy of Country Music Awards". there is a tinge of country in "California King Bed" but is that enough for a performance on that stage? and if thats all dandy, do we have another single comming soon? we'll just wait is all!
ps the song is mind blowing laced with epic rihanna vocals!
