Bar Refaeli 's Summer of envy-inducing fun continues! Bar flaunted her toned figure in a string bikini while hanging out with friends on a yacht in Formentera, Spain, on Sunday. She and her pals posed for pictures and videos, which the snap-happy model later shared on her Instagram feed , and Bar even changed into a printed one-piece to do some Jet-Skiing in the ocean. The bikini boat day is just the latest excursion for Bar, who has been documenting her Summer fun  through social media — she's been spending the past few months in her native Tel-Aviv as she hosts The X Factor Israel but has clearly been making time for lots of rest, relaxation, and swimsuits.
After taking the number three spot last year, Bar's flawless figure is back in our 2013 POPSUGAR Bikini Bracket. Make sure you vote for your favorite celebrity physique  for a chance to win a tropical vacation of your own!
