They're two of the world's most photographed women, and never fail to raise an eyebrow or two when it comes to their penchant for racy attire.
And Rihanna and Kim Kardashian came together for a good cause as they attended the singer's first-ever Annual Diamond Ball at The Vineyard in Beverly Hills on Thursday night.
The 26-year-old pop princess positively towered over the diminutive reality star as they enjoyed a good chat as the charity event, held in honour of the Clara Lionel Foundation, before working their magic in front of the camera.

The girls opted for rather different outfits for the occasion, with the Rude Boy hitmaker ditching her usual racy and revealing attire in favour of something a little more elegant.
Displaying her toned curves in all their glory, the Bajan beauty positively smouldered as she hit the red carpet in a breathtaking Zac Posen Fall 2014 Rose Stretch Duchesse Off-The-Shoulder Gown.
Although this was a pleasingly graceful and new look for her, Rihanna still managed to show off some cleavage highlighted by a glittering red stone and diamond pendant necklace.
Her tattooed wrist was adorned with a purple bracelet while dark red lipstick lent a dramatic effect to her features.
Rihanna raised the bar by wearing her hair slicked back into a long ponytail.
