Wedding season is upon us, and even stars aren't immune to it!
Rihanna celebrated her assistant Jennifer Rosales' nuptials in Hawaii on Monday and served as her bridesmaid, posting several snaps on Instagram throughout the day.
The "B-tch Better Have My Money" singer, 27, stepped into a gorgeous lilac Badgley Mischka dress in keeping with the bride's stunning, purple-hued theme.
Rosales has worked with the Barbadian singer since her 2007 "Good Girl Gone Bad" album, which brought us hits like "Umbrella" and "Shut Up And Drive." The pair have since become close friends, and Rosales makes frequent appearances on Rihanna's Instagram account.
In addition to the couple's happy day, Monday was the stoner's holiday 4/20 -- and the Trinidadian singer, celebrated (how else?) with what appears to be an illicit substance in hand.
See Rih walking down the aisle ... now that's a lucky groomsman!
