How can we forget when Rihanna overpowered the red carpet in her emerald green satin Dolce & Gabbana gown? It looks like Billy Joel's wife, Katie Lee Joel, was green with envy because she selected the same mesmerizing dress for a recent event. Both ladies look stunning, but I don't understand why Katie blocked her dress with her hair. Rihanna is more polished while Katie's more at ease. Which gal wins you over?
