Day one of the PopSugar Bikini Bracket is off to a great start, and after thousands of votes, we're giving you a sneak peek at the top five! Halle Berry's sexy frame jumped right to the lead, though last year's winner, Jennifer Aniston, is right on her heels. Victoria's Secret model Miranda Kerr slipped into a two-piece just months after giving birth to baby Flynn, and that's one reason she's in third. Following closely behind is supermodel Gisele Bundchen, who knows how to work every angle of a tiny bikini, and Kristen Stewart is holding on tight in fifth thanks to her hot Breaking Dawn Part I two-piece photos. Your votes count, so fill out your bikini bracket and enter for a chance to win $1,000 from J.Crew!
