Joss Stone vacations in Barbados with British musician Lemar

A self-confessed taste for Cornish pasties makes her the curvy girl she is. Or rather was. As Joss Stone shows in this pink and green bikini, there is a little less to her these days. A generous midriff has given way to a taut "six-pack" while her arms seem to be much more toned. Sunbathing on a private yacht in Barbados is hardly the toughest of workouts. But it seems to have worked wonders for 19-year-old Miss Stone, who was accompanied by 28-year-old musician Lemar Obika. "Joss has been out in the Caribbean, working on new material for her new album," said a source close to the singer. "Although she has not been consciously dieting, she has been eating a lot more healthily than she does back in the UK. "She has been upping her intake of plantain, avocados and sweet potatoes, which are all popular in the West Indies - and has lost the weight without really trying." Miss Stone recently professed to an appetite for Cornish pasties. "I'm a pasty girl all the way. Forget once a week, I like to have one every day." [DailyMail]
