Miranda and Orlando Show PDA at a Green Pre-Oscars Bash

Miranda Kerr and Orlando Bloom showed PDA at Global Green's pre-Oscars party in LA last night. The couple giggled and smiled as they walked the green carpet together, and Miranda, in a Peter Pilotto dress, even grabbed her husband's bum at one point in front of the cameras. The loving didn't stop once Miranda and Orlando got inside the event. They cuddled in their seats as they watched Willie Nelson perform for an audience that also included Helen Hunt and Sophia Bush.

Miranda and Orlando are big supporters of Global Green, even attending a climate change rally Sunday for the organization. Of course, the week hasn't only been about charity work for the couple — over the weekend, Miranda wore a black bikini to join Orlando and their son, Flynn, at the beach.
