Rihanna seems to be tired of showing her boobies under her see-thru outfits and she's now opted to show her ass.Most likely to add some spice to the life of her devout fans, and during her performance on Good Morning America, the sexy Caribbean singer lifted her already short skirt and showed the world her round booty.Granted, she was wearing panties and even pantyhose, but this Rihanna Upskirt incident is well worth mentioning. As you can see, she has nothing to envy Jessica Alba in the ass department. Those butt-cheeks are hard as a tortoise shell and rounder than a soccer ball!
