Miranda Kerr sported a bright, summery dress and blue fascinator for a photo shoot in Sydney today. Miranda's trip Down Under serves two purposes: she's modeling for David Jones, and it's the first time she brought her son to her native country. Miranda and very smiley baby Flynn touched down in Australia last week, and since then she's been fulfilling her duties for the fashion line with a photo call and posing here in their latest collection. The shoot had a day-at-the-races theme, complete with a white horse who Miranda pet between takes. Even when Flynn isn't along for the work day, he's never far from Miranda's mind. In an interview with the Sydney Morning Herald, Miranda revealed that Flynn is a little "bundle of joy" and husband Orlando Bloom helps with the diapers. While according to Miranda, they do hope to have another baby one day, they're overjoyed with 6-month-old Flynn for the moment.
