HTV catches Arnie Klein outside "Larry King Live," where the former dermatologist to Michael Jackson talks about the late singer -- and rumors that he fathered Jackson's children.

"Michael was the most generous person I've ever met," he tells the cameras. He goes on to talk about Michael's many charitable contributions and saying, "Don't vilify him. He changed the world."

"It was my honor to be his doctor and his friend," he adds.
