I think a beyonce & rihanna duet would be amazing on the charts & most likely would score them another #1 each .However unless beyonce plans to go with the rest of the "R&B" (Dance/House) the single would be a billboard crossover hit & id welcome it.Get my acapella ep here & download & listen to it please! http://www.mediafire.com/?wmd7jxbrwzho6re
