COMING OUT PARTY? IS RIHANNA AND CHRIS BROWN ENGAGED? SHE'S SPORTING A RING

Coming out party...They're back: Chris Brown and his girlfriend Rihanna sat in the front row at the Grammy Awards four years after his brutal attack on Ri Ri.  Sending an encrypted message? 

Rihanna caused a buzz on Twitter as she took to the stage for the Grammys wearing a simple diamond ring on her wedding finger on Sunday night.

And if that weren't enough, Rihanna sparked a storm of online speculation as she took to the stage wearing what appeared to be a diamond 'engagement ring' on her wedding finger.

Having shed the diamonds she wore on the red carpet, Rihanna replaced the bling with the simple band.

And as she gave her passionate performance, Twitter fans had their eyes firmly on her finger. 'Is that a wedding ring on Rihanna?' tweeted one excited user.

The hot-tempered 23-year-old Rihanna, who opted out of wearing a necktie, hopes his album Fortune will beat Frank Ocean and Miguel for Best Contemporary Album but didn't he must feel some kind of way about that shrug.




We Found Love singer Rihanna, who's since rekindled her love for Chris, looked absolutely elegant as she flashed a hint of cleavage in her crimson chiffon Azzedine Alaïa gown.

It's unclear how the singing pair are acquainted, but Brown probably had another lady-in-red on his mind - his on/off girlfriend Rihanna.

Rihanna already took home the first statue for Best Short Form Music Video for her song We Found Love, and she is scheduled to perform with Bruno Mars and Sting.

On Saturday, Chris crashed his Porsche into a wall on the way to a children's charity event before meeting up with the Rude Boy singer at the Roc Nation pre-Grammy brunch.

The loved-up couple later joined each other in the front row of the Staples Center to watch the ceremony side-by-side.

'It's cool. I'm fine,' he told E!'s Ryan Seacrest. 'A little bit of bumps. I'm good though.'
