Macho guys love chihuahuas! The arty portrait up tight is of the late great Loki with her beloved Mickey Rourke. Loki became one of the world's most famous chihuahua by the time she showed up, at age seventeen, on the red carpet in two of these photos.

Mickey readily admits to having had some pretty severe emotional troubles along the years, and credits the love he has had from dogs with getting him through it. "I'm not going to get religious on your ass," he said, "but I truly believe God created dogs for a cause. They are the greatest companions a man could ever have."
