In "Just Go With It", she only looked to be around a couple inches taller than Jennifer Anioston, who is like, 5'5". But Aniston looked to be really tiny next to Nicole Kidman, who is 5'10". And both were barefoot in the scene (the hula contest).So, either Brooklyn Decker is shorter than that, like 5'7" or 5'8", or Aniston was wearing really tall heels next to her, as we never see both of them from the waist down standing next to each other to see if they were barefoot or one was wearing heels. She's also almost eye to eye with Adam Sandler, which if she was 5'9", would only make Sandler 5'10", and I always thought he was like 6'1" or 6'2".
