Whoa! Joey Lawrence rescued a dog from a local animal shelter while filming in Australia. He called his new family member "the most amazing little thing ever." Another shelter dog—a pit bull who was rescued from a trash chute—has inspired Newark Mayor Cory Booker to build a new state-of-the-art animal shelter.

The former pres told David Letterman, "In deference to my diet, she'll be meatless that night."

Speaking of cruelty-free garb, The Veronicas sent flowers to Australian designer Rachel Gilbert to thank her for ditching fur.
