Dwayne Johnson sings 'Moana' to 3-year-old cancer patient

Former wrestler-turned-actor Dwayne 'The Rock' Johnson has performed an act of kindness for a three-year-old cancer patient by singing a song from Disney's 'Moana' to them.

It all began when Johnson heard about a little boy named Hyrum Harris, who has watched the Disney movie (in which The Rock voices the character of Maui) dozens of times. The Rock was touched by the fan's love of the film, so as a present he recorded himself singing the song "You're Welcome" to inspire him to keep fighting.

Watch the Rock sing to Hyrum in the video below:

The Rock took to Instagram to post a video of himself singing the song to the young Disney fan, and the performance has since gone viral on social media.

He captioned the video: "This request came across my desk and punched me in the gut a bit. There’s a little 3-year-old boy out there named, Hyrum Harris. Diagnosed with acute lymphoblastic leukemia which is complicated by Down Syndrome. [sic]"

He continued: "In the fight of his life right now and doing his best to stay strong - by watching MOANA up to 10xs a day because the character he loves, MAUI makes him feel strong. According to Hyrum’s mama, his most important thing to say now is, I STRONG. Yes you are big man. Yes you are. [sic]"

He added: "Hyrum, I know I’m a complete stranger to you - who sounds a lot like your hero, MAUI (only with a very large head), but myself along with millions of other strangers who will watch this video are sending you so much love, strength and mana your way. I STRONG. Love, the Rock aka the dude who sounds a lot like Maui. [sic]"

A GoFundMe has been set up for Hyrum is available for anyone who wishes to donate.
