Orlando Bloom got a massive workout when he walked around Runyon Canyon in LA yesterday. He had his 23-month-old son, Flynn Bloom, on his back, and the company of his dog, Sidi, as well as a friend and his canine companion as he made his way around the park. The trail is a favourite of Orlando's and he has been spotted exercising there plenty of times. His wife, Miranda Kerr, wasn't with them for the boys' day out, but the Kerr-Bloom family were together for Christmas and visited a friend in LA last week, putting to rest rumours that Orlando and Miranda's marriage was in trouble. The model became quite the domestic goddess over the holidays and posted a picture on Instagram of panna cotta desserts she made that were "a hit with my family this Christmas."
