Rihanna has poured even more fuel on the fire that she is back with Chris Brown after tweeting a topless picture of him passed out on a bed.

The singer - who has previously denied she is back with Chris - posted the snap of her ex-boyfriend half naked after they were seen spending Thanksgiving together in Berlin.

While his face wasn't visible, his trademark tattoos were on show - as well as his boxers - as RiRi tweeted: "Dis n***a....... #BartObsessed".

Rihanna - who later jetted to London to perform on last night's 'X Factor' - had been in Germany to see Chris perform as part of his Carpe Diem tour, just a day after finishing her own 777 tour.

A source told Metro: "Rihanna was supporting him for real though, kissing him a few times and you know... she was all about making Chris feel good."

However, in a recent interview Chris said that he and Rihanna were just "working on their friendship."

He told US radio station Power 106: "Me and her have history, and me and her are definitely always going to be best of friends."

His tweets to Jenny Johnson included: "Take them teeth out when u Sucking my d*** HOE" and "mom says hello... She told me not to s**** in ur mouth, wanted me to s*** right on the retina".

What a charmer.
