Roses too mainstream for you, Chris? In lieu of the typical V-day flowers, he presented Rihanna with a lovely bouquet of marijuana instead! RiRi tweeted out this picture last night, saying "Roses are green! Somebody knows how to make me happy." We just hope he also took her out to a really big dinner, or sent her lots and lots of chocolate- she might get hungry later! Do you think a bouquet like this is a thoughtful gift or just plain strange?
