Rihanna Promoting Beauty Line With Chris Brown’s Music in The Background

Have you heard Chris Brown's song "Come Together?"

If not, take a listen above to Rihanna's post ... okay fine you don't even have to do that because ima tell you right now it's that song she used!

She was promoting her makeup line and she had that song playing in that background. Granted this could all be for promo (clearly it's working) but what if she's hinting that they're friends friends?!

Okay, that's totally reaching but come on what am I supposed to think? I'm just so confused!

She captioned the post: "Gang Gang. just me and my#GlossyPosse!"

Anyone who knows what's going on, let me in!
