The Keeping Up With The Kardashians star took to her Twitter account to express her admiration for Rihanna's new album Loud, describing the singer as an "independent young lady".
In a separate message to Rihanna, she said: "From one goddess to another... Keep on shining! Everyone one loves watching! LOL :) keep showing them what you got! (sic)"
Rihanna later responded to the reality star: "Just when I thought I couldn't love u anymore.... thank u."
Kardashian is currently promoting her new unisex fragrance 'Unbreakable' and filming the debut season of her E! reality show with husband Lamar Odom, which is scheduled to premiere later this year.
Rihanna, featured in Kanye West's new single and its video, 'All Of The Lights', recently asked fans for their help in deciding which track from Loud should be released as her next single.
