Even though Karrueche Tran wore a very similar costume the other day, we have to say, Rihanna totally killed it as a living dead lady gangster!

The R&B superstar tweeted the above shots after getting her body painted blue and wrote, "ARLETA ZOMBIE CHOLA PACK!!! .... My chola name was #ShyGirl." A handful of RiRi's friends also dressed up like this, so even if Karrueche was somewhere nearby, we doubt she'd confront Rihanna about her copycat costume.
