The "We Found Love" artist has been spotted at multiple events with Chanel designer Karl Lagerfeld bedecked in the brand's famed double-C logo jewelry.
Rihanna tweeted in January that she had just wrapped a 'top-secret' ad campaign and has since tagged several of her Instagram photos with #CCcertified, referring to the brand's logo.
A spokesperson from Chanel denied the rumors in April, according to Vogue.
But Rihanna's recent trip to the Coco Chanel mansion has fashionistas' tongues wagging. She was photographed in the house, which has been maintained as Coco herself left it, sitting on her sofa.
Chanel typically chooses celebrities with a quieter reputation than Rihanna to represent the label. Nevertheless, Rihanna was pictured with Chanel designer Laetitia Crahay, prompting rumors of a campaign or collaboration.
