Gisele Bundchen walking with a friend in NYC

I'm trying to figure out whether Gisele or her friend is taller. It's like they switch height every other pic. I'm going to go with her friend because of the second picture.
 
im pretty sure her friend is another model, jill mccormick i think is her name. she's married to eddie vedder, the singer for pearl jam, theyve got a kid together. if it's not her, it looks JUST like her!
