Miranda Lambert and LeAnn Rimes will be joining Fox's 'The Great American Dog-a-Thon' this Thanksgiving.

The two-hour event, which will be hosted by actress Hilary Swank, will shine a spotlight on rescue dogs by sharing inspiring stories, videos and a salute to heroic canines. The event will also feature an awards ceremony with categories like Smartest Dog, Guiltiest Dog, Cutest Puppy and Best Licker.

Lambert and Rimes will be joined by fellow animal-loving celebs Paula Abdul, Kristen Bell, Josh Duhamel, Fergie, Carrie Ann Inaba, Scarlett JohanssonKesha and Betty White.

“I have long been an advocate for animal adoption and know first-hand the immense joy a shelter animal brings to our lives. Yet, every year, more than four million animals are euthanized because of overcrowding in shelters," Swank, who is also serving as co-executive producer, says. "We are so fortunate to have an animal advocate in the Fox network that not only sees the need for more awareness surrounding this issue, but is willing to set aside a two-hour block for this important cause. This partnership will change the path of a soul for thousands of animals looking for their forever home.”

During the program, local shelters will be giving viewers information about animals that are available for adoption. The show is set to air on Fox on Nov. 27 from 8 PM to 10 PM ET.
