Rihanna was one of 11 bridesmaids at her assistant and close friend Jennifer Morales' wedding in Hawaii on Monday. Jennifer was kind and allowed them to each wear a different dress, so long as they adhered to the purple dress code. Rihanna's interpretation? Lilac lipstick, obvs.
RiRi opted for a romantic lavender gown with kicked-out tulle at the skirt, a low sweeping back and silver flower detailing on the hip and skirt. She might have been one of 11, but Rihanna managed to stand out in the bridesmaid line-up. When the others smiled sweetly at the camera, Rihanna turned her back to the camera and did a mighty butt pop. When the grown ups stood up, RiRi crouched with the flower girls.
Rihanna isn't quite your typical bridesmaid, but judging by her Instagram she has thrown herself into the bridesmaid thing - even wearing a bright pink robe with the words 'bridesmaid' on the back.
Rihanna captioned an Instagram about the wedding: "#davis420wedding I can't believe this day is finally upon us!!!!!" she wrote. "I'm so happy and so proud to see my big sis @jennnrosales and my big bro @the_aa become one today!!! A wedding is a celebration of a marriage!!! That's what we gon do!!!
