Scarlett Johansson with her chihuahua and best friend Maggie (Top photo). In the middle photo left, Maggie is being walked by boyfriend Ryan Reynolds. Scarlett reportedly showed Maggie a great deal more affection than ever she did Ryan, so he moved on. Middle photo right shows Scarlett walking Maggie her own damned self. In the bottom photo, Scarlett and her buddy Natalie Portman vamp it up with Scarlett's chihuahua Maggie, who reportedly tore up the photo set-up just a little bit.
