Joss Stone at the 31st annual Kennedy Center Honors - arrivals at the Kennedy Centre, Washington DC, USA - 07.12.08

The You Had Me hitmaker, 21, had been dating 19-year-old boatbuilder Danny Radford since December (09).

But Radford has ended the romance to start a new life in France - after growing disillusioned with Stone's celebrity lifestyle, according to U.K. newspaper The Sun.

A source tells the publication, "Danny adores Joss but he couldn't put up with her constantly being away. He's upset but wants to make a fresh start. Joss seems cool about it."
