Rihanna uploaded new shots of herself dressed as a goth gangster zombie for Halloween recently. The "Pour It Up" singer posed for the shots after news broke about Chris Brown going to rehab. 

According to E! Online, the 25-year-old singer instagrammed a topless picturing of herself prepping her Halloween costume on Wednesday.

RiRi looked as if she had on goth makeup, dark lipstick and a henna tattoo on her hand, but her natural cleavage grabbed attention in the shot, reported E!

But the Bajan beauty later fully revealed herslef as a self-described "Zombie chola" in several other snaps. She wore Tommy Hilfiger boxers, sagging pants, a tiny bra-like stop and an open flannel shirt. And RiRi also had on big hop earrings and a bandana in her hair.

"My chola name was #ShyGirl," posted Rihanna. 

Aside from the creepy, unexpected costume, Rihanna's Bajan chef Esther made her an "epic phucking cake." The spooky dessert featured an edible witch, a cauldron filled with eyeballs, and a spell book.

Rihanna instagrammed a close-up of the spell book, covered slightly by an edible spider, which included an "Anti ba$ic recipe" of eye balls, spiderwebs, snakes, human brains, and liver.
