That said, the queen of the charts has revealed that the British aristocrat is actually one of her style icons.
Despite her upper crust background and royal profile, RiRi says Princess Di "was a gangsta with her clothes."
She told Us Glamour, "She was like - she killed it. Every look was right."
In terms of the history of fashion mavericks, Rihanna says she was "the best who ever did it".
Also making it onto the Diamond singer's list of inspirations was both Nicole Richie and her own mother.
She explained, "I used to watch her get dressed. She was around my age right now, and she was so fly. So fly."
Chances are we're not going to see the Bad Gal donning a skirt suit and loafers any time soon.
If her new video's anything to go by, she's happy with being R&B not real royalty.
