Miranda Kerr led her 1-year-old son Flynn Bloom by the hand through Sydney's airport yesterday. The little guy just celebrated his first birthday back in January, and he's already showing off his walking skills like a pro. Miranda and Flynn left the Australian city after a stay that included both work and play. She made a few promotional appearances for the Aussie department store David Jones, and also met with fans on behalf of her Kora Organics skincare line. Her husband Orlando Bloom has been busy as well, having traveled to New Zealand to shoot the next Hobbit movie. He's reportedly lined up another role, too. Orlando Bloom will appear in Zulu, a South Africa-based thriller from French director Jérôme Salle, costarring Djimon Hounsou.
