The 24-year-old 'Diamonds' hitmaker is still in touch with Brown after she denied their reunion recently, reported Ace Showbiz.
"Berlin and CarpeDiem," she tweeted on the same day, she was snapped attending the 'Look at Me Now' singer's concert in Berlin.
After watching the concert from an operation desk in front of the stage, where Brown was performing to promote his fifth album 'Fortune', Rihanna had a Thanksgiving bash together with him at a night club.
After partying, both singing superstars got into the same car.
Back in August, the 'Umbrella' jitmaker, who has just finished her 777 Tour, talked about her feeling towards Brown to Oprah Winfrey in an episode of "Oprah's Next Chapter".
"It's awkward because I still love him. I think he was the love of my life. He was my first love. We've been working on our friendship again and now we're very close friends," Rihanna had said.
