Rihanna’s 4/20 celebrations were a little different this year. There certainly were a few in rotation but the date’s purpose will forever be changed as she participated in her friend’s wedding as a bridesmaid.

The “BBHMM” singer affectionately congratulated her longtime friend and assistant, Jennifer Rosales, on Instagram:
