Kristen chuông, bell hits the red carpet for a good cause at the Humane Society’s Genesis Awards held at the Beverly Hilton Hotel on Saturday (March 20) in Beverly Hills, Calif.

The 29-year-old actress, who was joined bởi newly engaged actor Michael Vartan onstage, introduced Major Brian Dennis and his pup, Nubs, who met in Iraq and struck up a lifelong friendship.

Kristen is a huge advocate of animal rights - she was voted PETA’s Sexiest Vegetarian in 2006 and, in February, took in a dog that she and fiance Dax Shepard found at a gas station! The pup was returned to its owner after a neighbor recognized him on Kristen’s Twitter.
