FemaleFirst reports that the British singer has had several secret dates with the 33-year-old American rapper, who is 12 years older than Stone, and she is smitten with him.
A source revealed, "Joss and Nelly have been out on a few dates. It’s early days but Joss is really happy. It’s great that she has met someone as successful as she is and who understands the pressures of being a performer."
Stone has not been involved in a serious relationship since the breakup with Beau Dozier, who was her long-time boyfriend.
