They are clearly doing a lot more than just collaborating on music these days.
On Wednesday afternoon, following her controversial 777 tour, Rihanna Tweeted a photo of herself alone on a private plane, accompanying the image with the following caption:
All alone in my big ole jet!!! See u soon lover.
The destination of the flight? Berlin, Germany. The act performing in that city yesterday as part of his Carpe Diem Tour?
In case there was then any doubt over her holiday plans and with whom she would spend them, Rihanna added: "#Berlin #CarpeDiem."
She and her violent ex were then photographed last night at a nightclub in the area.
Indeed, Rihanna and Brown may want to believe their rekindled relationship is "Nobody's Business," but the singer clearly chooses to make it so when she alerts fans to her whereabouts in such a fashion.
Let's just hope she ended this encounter with Team Breezy's most famous member unscathed.
