Rihanna Hosts 1st Annual Diamond Ball with Brad Pitt, Kim Kardashian, & Big Sean

Rihanna rolled out the red carpet at her first annual Diamond Ball, a black-tie fundraising gala benefitting the Clara Lionel Foundation. Hosted by Jimmy Kimmel, the star-studded affair took place at The Vineyard, a private 157-acre enclave in Beverly Hills, on Thursday night.

The pop megastar arrived in a pink satin off-the-shoulder gown by Zac Posen, and was joined by her family including her mother, father, grandfather, and brothers before heading inside for the extravagant dinner and auction.

During the reception, Rihanna took the stage to talk about her foundation and kick off the auction, which included VIP tickets to Kanye West’s 2015 tour. Salma Hayek bid on a Damien Hirst piece for $190,000, while Big Sean was outbid on a $39,000 Gucci package.

Following an introduction from Brad Pitt, Rihanna, who changed into a midnight blue Zac Posen ball gown, performed her hits including “Diamonds,” “Umbrella,” “Pour It Up,” and “Take a Bow,” accompanied by a live orchestra.

Big Sean closed out the evening with “Clique” and his latest anthem “I Don’t Fuck With You” as Fabolous, Adrienne Bailon, Ellen Pompeo, and RiRi sang along.

The 600-person guest list also included Kim Kardashian, Kris Jenner, Naomi Campbell, Ne-Yo, Holly Robinson Peete, DJ Mustard, Tia Mowry-Hardrict, Lewis Hamilton, Terrence J, No ID, Tyrese, and more.

All proceeds from the event benefitted Rihanna’s Clara Lionel Foundation, which works to improve the quality of life for global communities in the areas of health, education, arts, and culture.
