The singer attended the festival last weekend, and uploaded an photo of her outfit to Instagram, complete with multi-coloured feathers and a jewel-encrusted bikini.
The elaborated look has been praised by fans, with one hailing her as a “goddess”.
Another said: “Best to ever exist.”
The photo also attracted unlikely attention from Chris Brown, who left a winking emoji in the comments before he was promptly condemned by the singer’s fans.
Defending Rihanna, one fan wrote: “Rihanna don’t need this kind of negativity in her life”.
“Can Riri flourish in peace?”, another asked.
Another high-profile comment came from Lorde, who simply wrote: “I’m DEAD.”
