Hear 'Pour It Up' like you've never heard it before.
Last week Rihanna threw the very first annual 'Diamonds Ball,' with guests amongst the Kardashian clan and Big Sean, and celebrated the occasion with some very special performances.
Wearing a gorgeous midnight blue ball gown, the 'Stay' singer performed hit songs 'Diamonds' and 'Pour It Up' in front of a full orchestra and at one moment even made it her business to conduct them.
The fundraiser for the The Clara Lionel Foundation, an organisation named after Rihanna's grandparents, aims to "improve the quality of life for communities globally in the areas of health, education, arts, and culture."
