You just knew she wasn't going to miss this opportunity!
On Saturday, Rihanna made sure to take part in the festivities on 4/20, also known as the unofficial day for marijuana connoisseurs, when she posted a picture indulging in a "special" cigarette after exhibiting some pretty risque moves on stage during this leg of her Diamonds world tour.
The 25-year-old pop star even sweetened the deal with a aptly themed cake to celebrate! She sure isn't shy about it, huh?
