Chris Brown Back To Twitter, Posts Photo Of Rihanna

Chris Brown re-activated his Twitter account Sunday, following an online dispute he had with comedian Jenny Johnson regarding his physical assault on ex-girlfriend Rihanna back in 2009.  

Though users can view his Twitter page once again, the "Don't Wake Me Up" singer has not tweeted anything at time of publication, and all past tweets and uploaded pictures have since been deleted.

Brown has, however, been active on his NFSW Instagram account, where he uploaded a picture of him and Rihanna on Sunday morning with the caption, "What would music today sound like if these kids didn't exist?"

Rihanna posted pictures of Brown on her Instagram page as well, including one last week of him lying shirtless on a bed.

Brown deleted his Twitter account last week after engaging in an online feud with Johnson. It began when the singer posted a picture of himself on Twitter with the caption, "I look old as f---! I'm only 23." Johnson responded on Twitter and said, "I know! Being a worthless piece of s--- can really age a person."

The two went back and forth cursing at each other and Johnson told Brown to "get some help," and even adding a link to an MTV article about Brown in court for the 2009 assault.

Brown ended by saying, "Just ask Rihanna if she mad??????"

Rihanna denied romance rumors regarding Brown in a Facebook Live! chat with Andy Cohen, saying that the two are not dating. However, the two can not seem to stay away from each other. They were spotted at a nightclub together in Berlin on Thanksgiving, and E! News reported that they left together and got into the same car.

Brown was in town for his "Carpe Diem" tour and Rihanna, who just finished her "777" tour in New York, traveled to Germany for the holiday.
