In a recent Twitter post, Rihanna posted a picture of Nicole Richie with the caption: This b*tch makes me throw up!! #bestdressed #2013metgala

Was Rihanna throwing shade? Not at all. This is just a nice way of saying how amazing Richie looked during Monday nights 2013 Met Gala. Richie nailed the “Punk: Chaos to Couture” theme with her freshly dyed gray hair, and gorgeous white embellished Topshop dress.

We agree, Richie makes us want to puke too #bestdressed.
