Rihanna & Chris Brown To Finally Go Public

In what clearly is the world's worst kept secret, Rihanna and Chris Brown will be finally going public by attending the 2013 Grammys… TOGETHER.

The two have been teasing us with their countless Instagram photos, like the latest one (above) showing RiRi in lingerie lounging next to Breezy.

Okay, yeah, we get it, you two are totally bumping uglies. And you love to smoke.

So, why the public "announcement?"

Well, since they're both nominated for Grammys this year, a source says:

"Rihanna wants to go together and he’s on board. Ain’t no hiding nothing anymore, all they s**t out and in the open. Rihanna told that him 'Don't trip on anything, you got this' and Chris was like 'Thanks baby, I know.'"

Does this mean we can expect a performance of their collab Nobodies Business???

Fingers crossed! Just keep the fireworks in the bedroom!
