Best and worst dressed at the Grammys!

J Lo, Beyonce, Rihanna and Lady Gaga - here's a look at all those who dazzled on the Grammys red carpet this year.

All eyes on the red carpet at Grammy Awards went straight to Lady Gaga and her solar-system gown that was totally out of this world.

Lady Gaga has become fashion's favorite chameleon and she didn't disappoint with this shiny, silvery, three-dimensional number that was created in collaboration with Giorgio Armani — and she promised other outfits throughout the show.
,br>"I am honored to be wearing Armani this evening. The series of pieces Mr Armani created for me are truly iconic; they represent not only beautiful fashion, but my spirit and essence as an artist," she said in a statement. (Photo: AP)
