We love it when the models bring their fresh, young friends along to the studio with them - naturally enough! This time it was Luisa, yesterday's girl of the day, who brought in her pal Lenka in with her to see what good friends they are. Just check the two of them out going girl-on-girl in Tuesday's photos! After the two of them were done shooting together, Lenka felt so at home in front of the camera that she stuck around to shoot another set with us. We think we've made a model out of her!
