Miranda Lambert posted a throwback photo with Joe Exotic, the much talked about star of the Tiger King docu-series. She explained that the picture was taken during Hurricane Harvey when Miranda's MuttNation went to Houston to help relocate shelter dogs to free up shelter space. The charity was looking for volunteers to transport dogs from Houston to Oklahoma, and Joe "volunteered his trailer and staff." Miranda wrote, I’ve never been to his zoo and I didn’t even know he had tigers. OBVIOUSLY I’d never condone animals being treated badly."
