Los Angeles: Hollywood star Brad Pitt will introduce singer Rihanna at her first annual Diamond Ball next month here.

The 26-year-old 'Stay' hitmaker will perform at the gala, which benefits Rihanna's Clara Lionel Foundation (CLF) and takes place on December 11, reported E! Online.

Comedian Jimmy Kimmel will host the soiree.

"It is such an honor to have Jimmy Kimmel host this event. There is no one more hilarious to make the first annual Diamond Ball an incredible night. I'm blessed by his support.
