Miranda Kerr stepped out for lunch Saturday at LA's Cheebo with her son Flynn. She's home again in California following a quick trip last week to South Korea, where she did interviews and had a few changes including a traditional South Korean costume, for photo ops on behalf of one of her many contracts. Miranda changed into an orange dress by the evening to attend a Global Green party at the Fairmont Miramar Hotel with her husband Orlando Bloom. They mingled with his Sympathy For Delicious director and costar Mark Ruffalo at the bash, which also brought out box office winner X-Men: First Class star Kevin Bacon and his wife Kyra Sedgwick. Orlando is a longtime celeb supporter of the eco organization, since both he and Miranda are well known for their advocacy on behalf of green causes.
