Rihanna made quite the statement with her canary yellow cape on the Met Gala red carpet Monday night, but that was just the beginning of Rih-mania.

Inside the Gala, she de-robed, then graced the stage in a red embroidered bustier and black silk pants to perform a few of her hits, including "Diamonds," "Pour It Up" and her most recent single, "Bitch Better Have My Money."

We can't blame her for taking off the cape, since she needed three train fixers to help her make it up the steps. Check out a few snippets of her performance below.
