Rihanna's Wearing a Huge Diamond Ring on THAT Finger — and She Hasn't Taken It Off

Over the past couple of months, Rihanna has been keeping her relationship with Saudi billionaire Hassan Jameel on the DL . . . until now. The singer was seen leaving Chris Rock's stand-up comedy show at Madison Square Garden wearing a head-turning ensemble. The songstress styled an embroidered Dolce & Gabbana jacket with a Céline tee, black pants, and hoop earrings.

Just a few days later, she was spotted yet again, this time for a night out at Avenue in NYC in a Balenciaga tee and denim trousers. But the most important accessory, which completed both looks, was a very special piece of jewelry on her ring finger: a massive diamond ring. While we're not sure whether this means the couple is engaged, we can take our time admiring it. Ahead, you can zoom in on the large champagne-colored stone, surrounded by white diamonds that create a daisy pattern.
