Rihanna hollywood hat dinner giorgio baldi singer marijuana joint

Rihanna was snapped leaving Giorgio Baldi in Santa Monica last night (c'mon, where else would she be?) and the 24-year-old R&B starlet was wearing a t-shirt detailing how to roll a joint!

Given some of the things RiRi has tweeted over the years (not to mention her song lyrics and some of the photos she's posted) it's no secret that she's a 420 lover, but she really seems to want the whole world to know! Hey, it's a free country...

In other RiRi news, on Saturday, the singer tweeted a sexy photo of Beyonce and wrote, "This pic could single handedly destroy the self esteem of an entire nation." Beyonce may be a stunner, but we think Rihanna is right up there with her!
