Rihanna slips into an elegant rose gown as she towers over tiny Kim Kardashian at her First Annual Diamond Ball

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.

Never far away: Kim's 'momager', Kris Jenner, also got in on the act, treating hostess with the mostess Rihanna to a huge hug inside the venue
