Rihanna and Chris Brown spent Thanksgiving evening together at a German nightclub.
The Barbadian singer ended her 777 tour in New York City on Tuesday and jetted to Berlin shortly after.
According to the New York Post, she attended Brown's Carpe Diem concert in the city on Thursday.
The pair were then seen leaving an after-party at Berlin's Adagio nightclub in the same car.
Rihanna heightened speculation about the status of their relationship after she posted a photo on her Instagram account on Wednesday en route to the German capital.
"All alone in my big ole jet!!! See u soon lover," she wrote.
"#Berlin #CarpeDiem," she tweeted the next day in reference to Brown's tour.
The status of Rihanna and Brown's relationship has been subject to intense scrutiny since he broke up with girlfriend Karrueche Tran last month and was seen out several times with Rihanna.
Both stars have denied being romantically involved since he was convicted of assaulting her in 2009.
They have admitted they are working on their friendship and since the incident have recorded three songs together: last year's Birthday Cake for her album Talk That Talk, a remix for Brown's Turn Up the Music released earlier this year, and Nobodies Business, for Rihanna's new album Unapologetic.
