The Diamonds singer, who is thought to have spent Thanksgiving with Brown in Berlin, took to Twitter to upload the snap - which showed the R&B star laying face down on a Bart Simpson duvet cover.
She accompanied the snap of Chris with the caption: "Dis n**ga....... #BartObsessed".
WENN reports that RiRi joined Brown in Germany after the end of her 777 jaunt, where she then watched the Don't Judge Me singer's Carpe Diem show at the O2 World Berlin concert venue.
The former couple were later seen together at the Adagio Nightclub, where they were snapped leaving in the same car.
The We Found Love hitmaker also seemed to reference her time with Brown in a cryptic tweet, stating: "All alone in my big ole jet!!! See u soon lover… Happy Thanksgiving everyone… #Berlin #Carpe Diem."
Despite these reports, Rihanna recently denied rekindling her relationship with Brown, insisting they were "not together" in an interview.
