Now that Miranda Kerr has come out and said she's pregnant, she has no need to try to hide her baby bump with baggy tops and whatnot. So she appears in a commercial for her Kora skin-care line in tight yoga clothes! And guess what: She's huge. Ha, kidding, she's not huge at all, she's skinny as ever and just looks like she has a throw pillow under her tank top. We're posting the full ad so you can see her baby body in action, but also because it's fun to hear a model say, "Our skin is the largest organ" and other things about, um, science.
