Glowing. Stunning. Ravishing.

Last weekend, Rihanna attended her best friend's wedding as a bridesmaid. She looked stunning in a royal blue dress, which went down the traditional route and matched with all of the ten bridesmaids that were there. The singer returned to her native Barbados over the weekend to be by her longtime pal Sonita Alexander's side on her wedding day.

The gals were having a ball all day, with the morning kicking off with glam time where they wore silk robes and took selfies together.

Knowing that Rihanna has had the same friends since childhood as made us love her that little bit more, and it seems she always steps up when needed.

She also flew over to Hawaii in 2015 to be  bridesmaid for her other friend Jennifer Rosales' wedding on April 20. On that occasion she wore a gorgeous lilac gown, with her hair in an updo. We have to say, she never seems to take away from the limelight of her BFFs on their big days, and we'd actually love to party with her all night long - could RiRi be the ultimate bridesmaid? We certainly think so...
