The Rock’s biggest muscle is his heart.

Dwayne “The Rock” Johnson was cookin’ up some healing vibes for a very special fan on Tuesday.

The Baywatch star choked back tears in an emotional video dedicated to Justin Rodriguez, a 12-year-old from Lawton, Oklahoma who has an inoperable brain tumor. After recently finding out that he has just weeks to live, Rodriguez made a bucket list of things to do before he dies that includes meeting The Rock, getting a tattoo, watching the Oklahoma City Thunder play, going on a trip to the beach, and helping his mom pick out her wedding dress.

Johnson was more than happy to help the brave youngster check something off that list. “I believe in my bones there’s power and positivity in sending uplifting love and energy,” the Hollywood heavyweight said in the surprise video shared to his personal Instagram page. “Justin stay strong, I’m pulling for you, the world is pulling for you. I love you buddy and stay strong.”

 

 

 

And The Rock proves yet again that his heart is his biggest muscle.

You can donate to Justin’s medical bills on the family’s GoFundMe page, and follow along as he completes his bucket list on Facebook.
