You know that super hush-hush birthday party I told you about earlier that Chris Brown attended for his ex RiRi? Well, there was a really awesome cake there…addressed to Ri’s real name “Robyn” to keep the party under wraps as much as possible. Obviously that didn’t work, since even TMZ is reporting on the story now! Ah man! Check out the super cool cake below, which involves a giant blunt and a caked out Rihanna on top of it! LOL!
