Rihanna posts topless picture of Chris Brown on Twitter

Last month sources close to the couple insisted they were ready to stop sneaking around and would take their reunion public

Rihanna has shared a topless picture of Chris Brown with her fans.

The Diamonds singer - who recently claimed she and Chris are just friends - posted the photograph of the Don't Wake Me Up singer lying face down on a bed on her twitter page after joining the 23-year-old singer on his tour in Germany.

The intimate image - which is reportedly the first time she has ever a personal photograph of her on-again/off-again boyfriend - came just days after they were spotted kissing and cuddling at Adagio club in Berlin after his gig.

A source previously said: "Rihanna was supporting him for real though, kissed him a few times and you know... she was all about making Chris feel good and being there for him. She made it all about him and took a back seat, so he could do his thing and let the fans [interact with him]. She knows he's on tour and the club was packed for him, so she was cool with it. Rihanna is loving the tour - she thinks he's performing well and she's showing Chris much love. They left together after the club, they're both enjoying their time together."

Last month sources close to the couple insisted they were ready to stop sneaking around and would take their reunion public after Rihanna released her new album Unapologetic - which hit the charts last week.

The insider said: "As soon as she finishes up with this album, they will be out. She gotta focus and get that album together and stay paid."

The 24-year-old popstar also posted a romantic tweet shortly before arriving in Berlin to celebrate Thanksgiving with Chris, suggesting they are now happy for fans to know they are back together.

She wrote: "All along in my big ole jet!!! See u soon lover (sic)"

She later shared a picture of couples kissing on a docked ship with the words: "Sometimes ya gotta do whatchata gotta do to get it done (sic)."
