Rihanna hosted her second Annual Diamond Ball for the Clara Lionel Foundation in Santa Monica last night, and the stars were out in force - as were her entire family. Here she is pictured with her mother, Monica Braithwaite (on the right there), and her father Ronald Fenty. 
For a closer gander at what Rihanna was sporting to her event, it's Dior with Cartier jewellery. Elle.com has gone so far as to describe it as "fancy bathrobe glamour."
As for her guests, we have Jada Pinkett-Smith (in Zuhair Murad) alongside long suffering husband Will Smith.
We also have Emily Ratajkowski stunning in black, with Kylie Jenner opting for a pale fishtailed number.
Other notable looks from the night come from Zendaya (that's not a skirt, rather some major palazzo pants action)... I
Isabella Lindblom's leggy number...
"TV Personality" Stephanie Bauer's top of her jumpsuit, which isn't at all reminiscent of anything...
And actress Alex Spencer in a rather transparent number, who brought model Bambi Northwood-Blythe as a buffer.
