Celebrity news has learned that CHRIS BROWN and RIHANNA cuddled up to each other in the audience at the 2013 Grammy Awards on Sunday.

Yep, it’s official all right.

Chris Brown and Rihanna sure had no problem about showing some PDA and leaning against each other (see the photo HERE) when they attended the 55th Annual Grammy Awards at the Staples Center. After all, we’ve been warned by their interview… they do have something going on and it’s nobody else’s business.

Regardless, the sight of the two together that evening was a tad bit shocking, considering their horrific altercation-for which Brown is still in probation for-took place on the eve of the 2009 Grammys.

It’s only been 4 years but they seem to have forgotten about it completely, based on their big smiles as they posed for photographers on Sunday night.

Are you okay with this or do you think it’s ridiculous that they’re going public now?
