Stars Pulled Out All the Stops For Rihanna's Glitzy Diamond Ball

Rihanna was the belle of the ball at her second annual Diamond Ball event in LA on Thursday night. The singer posed for photos in a stunning champagne-colored gown for the soirée, which is hosted by The Clara Lionel Foundation; founded in 2012, the organization works to improve the quality of life for communities worldwide in the areas of health, education, arts, and culture. She also brought her adorable niece Majesty on the carpet for a few sweet pictures. Before the fun began, a dapper Will Smith walked the red carpet with his gorgeous wife, Jada, while Emily Ratajkowski sizzled solo. Zendaya stunned in a sleek white two-piece ensemble, and Kylie Jenner arrived in a strapless number with a train with her boyfriend, Tyga.

Rihanna started The Clara Lionel Foundation in honor of her grandparents, Clara and Lionel Brathwaite, and has raised tens of millions of dollars for charitable causes in the three years since its inception. About the big bash, which was hosted by Kevin Hart, Rihanna told People this week, "It's overwhelming to see so many of the people that I care about come together to support a cause that is near and dear to my heart."
