Rihanna — I Got a BUNCH OF POT for Valentine’s Day

The way to Rihanna“s heart … is through her lungs … “cause the pop star says she got a WHOLE LOTTA MARIJUANA for Valentine”s Day … and she”s totally stoked.

Rihanna 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

We already know Chris Brown has a California weed card — so he can buy for HIMSELF in CA — but it”s against the law to buy pot for somebody else.

Still, Rihanna doesn”t seem concerned.
