Madonna has 52 years. Despite then she is very able-bodied woman. This however too little. Young, efficient and energetic Rihanna ( 22 years ) will win in cage fight. Both women are similar size. I think that their temperament and desire to fight are smilar. So the difference of age will decide. Madonna will fight bravely. But to the end fight Rihanna will beat Madonna until judge will to draw aside her.
