Rihanna Dresses Up As A Marijuana Bride (We Think!?), Parties With 'Basketball Wives' Star Evelyn Lozada On Halloween! (PHOTOS)

Rihanna chills with Evelyn Lozada at her annual Halloween party!

Rihanna's been pretty busy these days! In addition to celebrating her forthcoming Unapologetic disc with a "777" promotional tour, Ri has also found time to film her "Diamonds" video, enjoy a "nutritious" breakfast in bed, and plan a not-so-run-of-the-mill Halloween party. And we say "not-so-run-of-the-mill" because a) it was held at the Greystone Manor Supperclub in West Hollywood, and b) the event was billed as, get this -- the "2012 Halloween Carnival." OK, Rihanna -- you've got our attention! So, how was the party? Clearly it was pretty good, 'cause we see you were hanging out with Evelyn Lozada!

Check out more photos of Rihanna partying with Evelyn Lozada after the jump.

As evidenced by these perfectly filtered Instagram photos, Rihanna is rocking a green headdress, ring, and green dress, as well as a bouquet of marijuana (DO NOT TRY THAT AT HOME EVER EVER EVER!!!), while Evelyn came dressed as sexy Ariel from "The Little Mermaid." The "Basketball Wives" star tweeted, "My Halloween costume!! #Ariel #Mermaid" and  "My 2 loves Shaniece Rihanna, Team Rihanna 411 - Love u & thank u 4 a blessed night!" On a side note, Chris Brown came to the party too...dressed as a member of the Taliban. Dude definitely wins the "worst costume ever" award. Forever.
