Ryan Reynolds is saying goodbye to his friend "Bubba."

The actor, 39, took to Facebook to post a touching tribute to a young Deadpool fan who died after a battle with cancer.

"For three straight years, my friend, Connor McGrath drop-kicked cancer... Not sure how... Maybe the cancer cheated... But the fight came to an end two nights ago," he wrote. "In my wildest dreams, I can't imagine how hard this is for his parents Kim and Gerald—along with his extended family in Newfoundland."

Reynolds explained that he met McGrath, who was 13, through the Make-a-Wish Foundation, and the teen became one of the first people to see Deadpool before it hit theaters.

"I traveled up to Edmonton, Alberta, to surprise him with a rough cut of the film. There were still huge sections with wires we hadn't yet painted out, jokes which weren't working (and still aren't) and green screens," he wrote. "Connor didn't seem to mind. And I'd never felt luckier to get to be Wade Wilson."

"Before you jump down my throat for showing a 13-year-old an R-Rated film, please know this kid knew more swear words than a British chef," the actor added.

Along with the heartfelt message, the actor included a series of photos of the two together.

Reynolds explained that over the years, he formed a strong bond with McGrath, whom he describes as "smart" and "unqualified funny."

And as he got to know him, the actor said he began to see similarities between the boy and his Deadpool character.

"I called Connor, 'Bubba.' And he called me 'Bubba2.' We met because he loved Deadpool. In a certain sense he WAS Deadpool. Or, at least everything Deadpool aspires to be; balancing pain, fearlessness, love and a filthy (filthy!) sense of humor in one body," he wrote. "I wish he could've stuck around a lot longer."

"See ya down the road, Bubba," he concluded.
