Chris Pratt Celebrates a Young Fan Who Beat Cancer!

Now this is something to celebrate!

Chris Pratt shared good news via Facebook Thursday—and it had nothing to do with Guardians of the Galaxy receiving Academy Award nominations for Best Makeup and Hairstyling and Best Visual Effects.

"After a long battle with childhood leukemia, Emma is going home cancer free!!!" Chris announced.

Chris, 35, included a photo. "Atta girl! You kicked cancer's butt!!!" he wrote. "Thank you to Children's Hospital Orange County for setting up an amazing visit and to Emma for my wonderful painting." CHOC Children's replied to the Parks and Recreation star's sweet gesture via Twitter, writing, "Thank you SO much for visiting our patients! They had a blast. We appreciate your time and please come again soon!"

Anna Faris' husband, who was named GQ's Man of the Year in 2014, has a knack for making kids smile. Last summer, Chris surprised families involved with the Variety the Children's Charity of New York and Children of Promise following a Guardians of the Galaxy screening. "Take it from a kid who grew up having no money," he said. "If you stick to your path, and you believe in yourself and you be courageous enough to be yourself you can grow up, you can be your own Star-Lord." The actor also dressed up in costume as Peter Quill/Star-Lord when he visited patients at Children's Hospital Los Angeles. "If it was a big enough movie, to where it would mean something to a kid who's sick in the hospital for Peter Quill or Star-Lord to come visit them, I'll do that," Chris told Panzer TV in July. "I think that's awesome, man."

The actor supported another charity effort in December at March of Dimes' Celebration of Babies. Chris and Anna became parents nine weeks early when Jack Pratt was born in August 2012. At the time, their newborn son weighed just 3 lbs., 12 oz. During the event, Chris joked, "That's a decent-sized bass. Very small for a human." On a more serious note, he said, "I've done all kinds of cool things as an actor: I've jumped out of helicopters and done some daring stunts and played baseball in a professional stadium, but none of it means anything compared to being somebody's daddy." The Jurassic World star was shocked that "none of what we went through would be as easy even 10 years ago," and explained that in the NICU, life or death hangs in the balance—"a balance that's tipping towards life by cutting-edge medicines, much of which is a direct result of this wonderful organization, the March of Dimes."
