Two unsuspecting celebrities have developed a unique friendship after bonding over their love for animals: Slash and Betty White! The odd couple met through their involvement with animal activism in LA, and both the Guns N' Roses rocker and the 88-year-old Golden Girls alum are slated to participate in The Humane Society’s Diamonds Not Fur benefit this spring. “Slash and Betty White are both big animal advocates and we’re excited to have them at the charity event,” Katie Clearly, host of Diamonds Not Fur, tells In Touch. “It’s really cute, they have become good friends." Apparently, animals can bring all walks of life together!
