TMZRihanna posted her V-Day haul on Instagram … along with the message, “Roses are green! Somebody knows how to make me happy.” The question is … who got her the gift???

Do you like weed, Rihanna? Do ya? Huh??

The worst part is when you think about the kids. So many tweens out there idolize this chick and will copy any and everything she does. It’s a shame how much power this woman wields. Guaranteed by middle of next week there will be hundreds of 13 year-old girls out there twerking their little under-aged and under-developed bodies flaunting crappy seed and stem-filled nickel bags on Instagram trying to smoke like Rih Rih.

Seriously though…that’s a lot of weed.
