Rihanna acted as bridesmaid at the wedding of her assistant and close friend Jessica Morales on the weekend.
The celebration took place on a romantic beach in Honolulu, Hawaii.
RiRi certainly got into the role of 'maid! The 27-year-old superstar was pictured on Instagram wearing a satin robe embroidered with 'bridesmaid' and larking about with the bridal party.
Though her Badgley Mischka dress was a classic bridesmaid shade (lilac) with whimsical floral details, Rihanna amped up the fashion factor; the figure-hugging tulle gown had a glamorous low back, small train and an embellished waist.
The singer shared excited captions ahead of the nuptials on Instagram, saying "#davis420wedding I can't believe this day is finally upon us!!!!!"
She added, "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!!!"
We think Rihanna made one super cool bridesmaid, but what do you think? See the star in bridesmaid mode to decide!
