To clear up any confusion over which redhead is which, Jurassic World [1]'s Bryce Dallas Howard expressed in song that she is not, in fact, Jessica Chastain. She did a lip-sync video using Dubsmash, rocking sunglasses before revealing her face and declaring, "I am not Jessica Chastain!" To make it a bit more confusing, it's Jessica who shared the video on Instagram, but her caption spells it out: "Everyone get it yet? : ) performance by #BryceDallasHoward not #JessicaChastain." The post comes just a few days after Jessica shared a picture of the pair [2] and wrote, "True story. #BryceDallasHoward is in #JurassicWorld."
