The Ride Along star will be joined by singer Lionel Richie, who will perform at the black-tie fundraiser in Santa Monica, California on 10 December (15). The event will help raise funds for Rihanna's Clara Lionel Foundation, which was started in 2012 to help communities around the world "improve the quality of life for communities globally in the areas of health, education, arts and culture."

"I'm so proud of the work the Clara Lionel Foundation has done in its first year and can't wait to celebrate with the iconic Lionel Richie and incredibly talented Kevin Hart at this year's Diamond Ball," a statement from Rihanna reads.

During this year's event, the star will honour Live Nation CEO Michael Rapino with the inaugural Diamond Honors Award for his philanthropic work through the company.

"This foundation is close to my heart and I am so grateful for Michael Rapino's support and commitment to our cause," she continues. "No one is more deserving of the first Diamond Honors Award than him."

Last year (14), Rihanna helped to raise $2 million (GBP1.25 million) through her charity fundraiser to help provide equipment to a hospital in the 27 year old's native Barbados.
