Nicole Richie's Met Gala look made Rihanna 'throw up,' in a good way

Fashionista and newbie Internet star Nicole Richie stunned at Monday night's punk-themed Met Gala in floor-length TopShop dress accessorized by a fantastical gray updo.

Richie's look so inspired Rihanna, the 25-year-old pop singer Instagrammed a photo of the style with the caption, "This bitch makes me throw up!!"

Before you take her comment too seriously, Rihanna used the hashtag #bestdressed to let Richie, 31, know that her outfit was "sick," but in the best way possible.

Richie took the compliment, tweeting back a reference to one of Rihanna's latest singles.

Currently shining bright like a diamond, a ruby, & 2 emeralds. @rihanna
