Rihanna makes one seriously awesome bridesmaid -- not that we'd expect anything less.

The "FourFiveSeconds" singer was one of 11 bridesmaids in assistant Jennifer Rosales' wedding in Honolulu, Hawaii, on April 20. The ladies wore dresses in various shades of purple. Rihanna can be seen posing like a total boss in a lilac Badgley Mischka Couture gown in a photo from the beach affair.

Their friend Melissa Forde was also a bridesmaid and shared some other snapshots from the big day.

Before the ceremony, the 'maids hung out in satin robes and smoked because that's what awesome bridesmaids do on 4/20.
