Chris Brown and Rihanna Back Together? Stars Share Lovey-Dovey Photo on Twitter And Instagram [PHOTO]

Rihanna and Chris Brown appear to be back together, and not "friends only" together but "friends with benefits" together, after Rihanna posted the above pic on instagram along with the line : "@f-yopictures i don't wanna leave!!! Killed it tonight baby!!!"

@f-yopictures is Chris Brown's Instagram handle. He just finished a performance in Frankfurt, Germany. Apparently he "killed" it there. So much so that rihanna couldn't keep her hands (and legs and arms) off him backstage.

Rihanna also used instagram to let followers know where her "bad girl" mindset was at last night by also posting "Home is Where the C-k Is" Looks lke she's found home, or is close to finding it anyway.

Instagram has been the source of Chris Brown and Rihanna "back together" rumors for over a week. After spending Thanksgiving together in Berlin, Rihanna posted a shirtless pic of Brown in her bed.  Then she tweeted a shirtless pic of herself on Sunday. Oh, and the two are sporting matching Rolex watches.

"Don't believe me just watch #newtoy#justcusimnumber1 #roleylife #dopedealer," Rihanna tweeted along with the bling pics.

 "Unapologetic" is Rihanna's new no. 1 album. It also looks like it is the rallying cry for her on-again relationship with Brown.

Will people disapprove of the hook-up? Or is it time for everyone to get off Chris Brown's back already? Tell us in the comments!
