Model, new mom, and all-around hilarious person Chrissy Teigen has yet to get a handle on the physics of her mammoth new breastfeeding boobs. On Sunday, she posted an Instagram of herself, her boobs, and her husband John Legend on an amusement park ride (looks like Splash Mountain). There was no problem with keeping her hands inside the car at all times; Teigen got a firm grasp on her milk jugs, which probably tried to bounce around a little more than she expected. Her caption for the photo is just "MY MILK." Her face pretty much says the rest.
