Miranda Kerr stepped out solo yesterday to shop at the store Zimmerman in LA. The busy mom was making the retail rounds without her 4-month-old son Flynn during a break from her various modeling jobs. She's been doing lots of press for Victoria's Secret, and we caught up with her at a recent lunch to learn all about Miranda Kerr's postbaby fitness secrets. Miranda also spoke about her diet, saying she follows the "80 percent healthy, 20 percent indulgent" rule. Her husband, Orlando Bloom, has been occupied with his own fashion endeavor. He teamed up with Uniqlo, for whom he's modeled in the past, to design a t-shirt for Japan relief along with Lady Gaga, Blake Lively, and other stars.
