With the Grammy Awards approaching on Sunday, it's no surprise to see the stars aligning in Los Angeles for this year's round of preshow parties. Just last night saw Rihanna , Miley Cyrus , Taylor Swift , and tons of other talented entertainers looking chic.
Rihanna  went through two spectacular outfits yesterday, combining two sets of stripes for Roc Nation's pre-Grammys brunch before changing into a dramatic yellow gown for an evening gala. Taylor and Miley both shook up the red carpet at the same event, where Taylor chose one of Zuhair Murad's sparkly cocktail dresses and Miley dressed up in an all-pink look from Calvin Klein .
Earlier on the preparty circuit, singer Iggy Azalea donned a dramatic, long blue gown with a plunging neckline for the annual Friends 'n' Family Grammys Weekend Dinner, and Paris Hilton  paired a sheer black dress with the hottest accessory of the moment, an ear cuff . And at the MusiCares Person of the Year Awards, Lady Gaga  chose a white gown with a keyhole neckline.
