Ellen Looks Hotter Than Rihanna!

Rihanna stopped by The Ellen DeGeneres Show yesterday (it'll air on Monday) and she was wearing a most interesting rainbow-colored, 3D dress.

But I was less interested in Rihanna's dress and more shocked by the hostess' choice of clothing -- Ellen wasn't wearing her trademark slacks and sneakers but some skinny jeans and thigh-high patent leather boots!

I'm a huge fan of her usual preppy-cool style but we'd like to see her rock this sexy look more often. She just turned 52 on Tuesday and she looks hot!
