She may be @BadGalRiRi to us, but don't let that fool you – Rihanna is also a do-gooder.
The superstar announced on Thursday the first annual Diamond Ball to benefit the Clara Lionel Foundation, which aims to improve the quality of life for communities around the globe in the areas of health, education, arts and culture. The black tie event will take place on Dec. 11 at The Vineyard in Beverly Hills.
PICS: Rihanna's Most Buzzed-About Shots
Rih started the Clara Lionel Foundation in 2012 in honor of her grandparents, Clara and Lionel Braithwaite.
"There is truly nothing I'm more proud of and we've just gotten started," she said in a statement. "I'm excited to continue my work and thrilled to be able to host the Diamond Ball – a night that promises to be elegant and inspirational."
Rihanna was inspired to create the foundation after witnessing the shortcomings of the Barbados healthcare system first-hand as her grandmother battled cancer. The Clara Braithwaite Center for Oncology and Nuclear Medicine and Queen Elizabeth hospital was officially named in 2012, thanks to a large personal donation from the pop star.
A press release states that funds raised at this year's Diamond Ball will go toward improving the center, purchasing equipment and infrastructure planning – a projected $2.4 million cost.

Approximately 600 guests will be able to purchase table and ticket packages for the event, including a dinner, live auction and an intimate performance from Rihanna herself.

Rihanna also honored her late grandmother (aka "Dolly") in 2012 by getting a massive tattoo. The ink is of the Egyptian goddess Isis, with her wingspan spreading across the singer's ribcage. "Goddess Isis – Complete Woman – Model for future generations," Rihanna wrote on Instagram with the hashtag #GRANGRANDOLLY. "Always in and on my heart."
Just a few short days ago, Rihanna shared images from her grandfather's (aka "Bravo") birthday party, complete with sparkly hats and an even more sparkly cake.
While the 26-year-old has clearly been busy with her family (and winning Halloween with this hilarious costume), she may have also been quietly working on a new album. She's just one of the five stars that we hope might pull a Beyonce this year.
