In June 2022, nine months after a routine checkup revealed breast cancer, Beverly June Lambert was officially declared cancer-free and stepped straight back into running the national animal rescue foundation she built with her daughter, Miranda Lambert.
Long before Nashville knew Miranda’s name, Bev and her husband, former Dallas police officer Rick Lambert, worked as private investigators in East Texas while rebuilding their household after losing everything in a bankruptcy. Even in tight years, the couple opened their home to women and children escaping domestic violence, and Bev took the wheel as Miranda’s earliest manager on the Texas bar circuit.
In 2009, mother and daughter turned that practical habit of stepping in to help into the MuttNation Foundation, a nonprofit focused on shelter-pet adoption, spay-and-neuter programs, and emergency disaster transport. Over the next decade, Bev directed day-to-day shelter partnerships while Miranda headlined arenas.
That rhythm shifted in September 2021 when 62-year-old Bev received her breast cancer diagnosis. Following surgery in October 2021 to remove the tumor, she faced months of chemotherapy and radiation stretching into early 2022 while Rick, her son Luke, Miranda, and Miranda’s husband, Brendan McLoughlin, kept the news out of the press.
Between contracted tour dates and finishing her album Palomino, Miranda repeatedly flew from Nashville back to Lindale, Texas, to cook meals and sit beside her mother during chemo rounds. On the day Bev decided to shave her head, Miranda was stuck out of town working and joined her mother and the hairdresser on FaceTime; once back in Texas, she stood behind Bev’s chair and rubbed essential oils onto her bare scalp.
Even at the height of treatment, the shelter work they started together never stalled. In March 2022, the same month Bev rang the hospital bell to mark the end of chemotherapy, MuttNation and Tractor Supply distributed more than $250,000 in surprise Mutts Across America grants to fifty-two animal rescues across every state.
By mid-June 2022, just days before Miranda went public with Bev’s clean bill of health in a June 29 People interview, she honored her mother and late grandmother, Wanda Louise Coker, by launching the Wanda June Home collection. Telling reporters that her mother’s illness reminded her nobody gets family forever, Miranda also blocked off the entire month of July to pull off the road.
With her port removed and short silver hair growing back, Bev returned at full speed to MuttNation’s fall schedule. When Hurricane Ian battered Florida in late September 2022, she and Miranda directed emergency relief grants to Humane Society Naples and Greater Good by October 6 to house and feed displaced pets, alongside funding flood repairs for a damaged shelter in Montana.
That same autumn, Miranda opened her Velvet Rodeo residency in Las Vegas. During the opening eight-show run, Bev showed up for nine nights, including rehearsals when the theater seats were still empty, and joined her daughter onstage during October’s Breast Cancer Awareness Month.
Looking back in January 2024 as Bev passed the one-year cancer-free mark, Miranda told television host Tamron Hall that watching the stress on her family gave her a new perspective on time.
By March 2023, the mother-daughter pair had expanded their disaster work by launching a dedicated Relief for Rescues fund, followed that June by another $250,000 round of shelter grants. Bev noted at the time that finding deserving rescues across the country was easy, while narrowing the list to one per state remained the real challenge.
Together, their foundation has now raised more than $13 million for shelter animals nationwide. Years after Miranda rubbed oil onto her mother’s bald head in an East Texas house, the former private investigator who drove a teenager to honky-tonks is still reviewing grant applications beside her daughter and showing up early before the auditorium doors open.
