A bikini-clad Bar Refaeli and her boyfriend, David Fisher, were back on the water today yachting with friends off the coast of Porto Cervo, Italy. Bar slipped into another jewel-toned bikini to soak up the sun following a romantic walk along the shore with David. The seafaring couple have been inseparable since arriving on the Mediterranean coast, though she did sneak in a dinner with close friend Vale Micchetti last night. Meanwhile, around the globe Bar's former beau Leonardo DiCaprio is still making a go at it with Blake Lively. Leo and Blake were spotted leaving a Stevie Wonder concert at LA's Hollywood Bowl over the weekend. Bar's bronzed body is among the leaders in this year's PopSugar Bikini Bracket — don't forget to fill out your bracket for a chance to win $1,000 from J.Crew!
