Chris Brown Back to Twitter following Vulgar Jenny Johnson Feud: Posts Instagram Photo Smoking, Hanging with Sexy Rihanna [PHOTO]

Following his heated and vulgar Twitter feud with comedian Jenny Johnson last week, R&B crooner Chris Brown is finally back on the popular social networking site, but so far it looks like the 23-year-old is keeping his blunt and irrational tweets to a bare minimum. But that doesn't mean the "Don't Wake Me Up" singer is keeping quiet on Instagram! While Brown reactivated his Twitter feed on Sunday (Dec. 2), no tweets have yet been shared and all of his previous tweets have since been deleted (guess he doesn't have anything to say about the explicit verbal confrontation with Johnson... at least not yet!). But Brown did share an intimate photo hanging with a scantily-clad Rihanna while puffing (on a joint) on a couch. Now that's the true RiRi and Brown couple fans know and love!

Just last week, Brown got into a rather offensive Twitter feud with comedian Jenny Johnson which ended with Brown's last tweet reading, "Just ask Rihanna if she mad??????" Then he deleted his account while Johnson was left victim to several scary death threats and cyber abuse. For the full story and Twitter convo, go here.

Now Brown is back, and although he hasn't sent out any "enlightening" tweets yet, his over 11,690,000 followers can rejoice in his return to Twitter world.

In the meantime, Brown is making good use of his Instagram account to reaffirm the rumors that he and Barbadian songstress Rihanna are definitely kind-of-sort-of back together (reunited with their mutual love for Mary Jane). Check it out:

Rihanna hasn't been shy about posting intimate photos hanging with her man either:

And apparently the two plan on spending the holidays together with RiRi's friends and family in Barbados. So maybe Brown's Twitter will start getting some sexy Twitpic love soon!
