The Diamonds World Tour touched down in Amsterdam this weekend, with?Rihanna scheduled to play two shows at the Ziggo Dome. Naturally, upon arriving, the 25-year-old singer celebrated with a treat the city is famous for. On Saturday, RiRi posted several photos on Instagram documenting her cloudy adventures with one of her BFFs Jennifer Rosales. While on tour in Amsterdam, Rihanna was seen smoking pot in public, and the singer did little to hide her drug-use posting pictures of herself smoking to Instagram. Yet another yucky decision by Chris Brown! The bad boy reportedly wants nothing to do with Rihanna anymore, even if it means cutting her moneymaking voice from his upcoming album, collection X!
