Looks like Rihanna and her beau Chris Brown may be taking a walk down the aisle.

The sexy songstress left a post-Grammy party at Supperclub sporting what looks like an engagement band on her ring finger.

Good thing Chris has recovered from Saturday's car accident in which the R&B singer totaled his black Porsche. Brown was en route from the Debbie Allen Studio in Los Angeles for a Symphonic Love Foundation event, and according to police, he crashed his car into a wall in Beverly Hills because he was trying to elude the paparazzi. His ladylove Rihanna was there to comfort him shortly after the wreck. And this bright orange Lamborghini is a sweet replacement ride.

Aside from the accident drama, Brown's on-again-off-again-on-again relationship with RiRi is back under a microscope.

Four years ago, after leaving a Grammys party, Chris Brown brutally assaulted Rihanna ... leaving her bloodied and bruised. During last night's awards show, the twosome were all smiles. What a difference four years makes.
