Guess Which Sexy Model This Adorable Kid Grew Up To Be! (PHOTOS)

Who knew that this adorable little trendsetter would grow into one of the sexiest Sports Illustrated models of our time? 

Bar Refaeli tweeted the above photo of herself out to followers with a caption that read "Little B." 

Little B was sporting a pair of blunt bangs that carefully grazed her piercing blue baby eyes.

Times have certainly changed since Bar grew up to be a beautiful swimsuit model, but one thing that hasn't changed is the hipness of Little B's statement bangs.
