See photos of Rihanna at her first Annual Diamond Ball

Rihanna held her Diamond Charity Ball event at Vineyard in Beverly Hills.

And the 26-year-old pop princess stole the whole spotlight with an elegant breath taking rose coloured off-shoulder gown with a dramatic train.  She showed off some cleavage highlighted by a glittering red stone and diamond pendant necklace.

Her tattooed wrist was adored with a purple bracelet and dark red lipstick lent a dramatic effect to her features.
