Rihanna has sparked rumors she is engaged to R+B singer Chris Brown after she was photographed wearing a diamond ring on her wedding finger.

The Bajan beauty has been romantically linked to the Kiss Kiss hitmaker for months, but both singers have continually denied they are a couple, despite being snapped in public kissing and cuddling.

The pair stepped up speculation about their relationship last week when they were snapped frolicking in a hot tub together in Los Angeles.

And now Rihanna has fuelled rumors that they are to walk down the aisle after she was snapped sporting a ring on her left hand.
