Spending her holiday dressed up for a deserving cause, Rihanna main attraction at a Halloween costume ball in Tinseltown on Wednesday night (October 31).

Held at the Greystone Manor Supperclub, the 24-year-old songstress rocked a tamer than expected black dress with a tiara atop her curly coif while joining alongside West Hollywood Councilmembers John J. Duran and John Heilman and West Hollywood Mayor Pro Tempore Abbe Land in the devil's night celebration.

During the course of the festivities, RiRi was doted with roses and a certificate while being honorarily named Queen of the West Hollywood Halloween Carnaval.

Those in attendance at the "costume mandatory" event not only got a chance to party with the Barbadian beauty, as they also enjoyed music by DJ Reflex.

As for the cause, the Clara Lionel Foundation helps to bring clothing and shoes to needy persons and at-risk populations, as well as offering social skills and counseling for underserved communities.
