Seven-year-old Gabriel Singleton has been fighting cancer for more than four years. The young boy, who is affectionately known as “Tater,” was diagnosed with stage 4 neuroblastoma when he was only 3 years old. Throughout his battle with the disease, Tater has looked up to one person in particular for inspiration: Dwayne “The Rock” Johnson.

“He was kind of embarrassed about his bald head. So I would pull up The Rock’s Instagram account and I’d say, ‘Look! The Rock is bald and he’s so strong and he’s awesome. You’re just like him,'” Lulu Singelton, Tater’s mom, told WRCBTV.

Now, Tater is using social media to reach out to the former wrestler in hopes of meeting him. The Children’s Hospital at Erlanger in Chattanooga, Tenn., posted a picture to its Facebook page on Wednesday of a poster showcasing the boy’s message to Johnson. “I think you are strong, but I am very strong too,” it reads. “I’ve been stuck by hundreds of needles, have had tons of shots, gone though eight surgeries, too many blood and platelet transfusions, lots and lots of chemo treatments, radiation therapy, tests, scans and two stem cell transplants!”

The sign also asks for people to share the post in order to spread the word to The Rock. It has been shared over 3,000 times to date.
