Dwayne Johnson delighted a young Moana fan battling cancer as he serenaded her with a song from the movie.
The retired wrestler spent his 49th birthday reaching out to the four-year-old girl via an Instagram video. The sweet post saw the actor sing 'You're Welcome' - the tune his character Maui belts out in the 2016 Disney flick.
Check out the adorable video here:In the sweet video, Johnson says: "This goes out to a very special and very strong little girl. Her name is Indy Llew.
"A friend of mine just sent me this awesome video of a young girl singing 'How Far I'll Go' from the movie Moana."
He then jokes: "Now I know you have no idea who I am, and that's totally cool but I was in Moana. I'm Maui. I know, where's my hair?"
The wrestler-turned-actor then proceeds to perform his own personal rendition of 'You're Welcome' for little Indy.
He captioned the post: "It's 1am and I just got sent this beautiful vid of a VERY special & strong little girl named Indy Llew Stay strong honey and keep singing your songs! Love you, MAUI."
The post has since managed to rack up 4.4 million likes and over 39,000 comments.
Celebrities and fans alike flocked to the comments section to praise the Baywatch star for his kind gesture, with rapper Big Sean writing: "Amazing!!! Your Heart is bigger than you! Happy Birthday brother!!! Love n thank you for all you do and inspire us to do."
Another wrote: "I AM CRYING. You are such a special human and sending so much love to that sweet angel girl and her family."
A third person shared: "Great vid to watch before bed! Maybe a Maui & Indy collab?"
Indy's mom, Terah Jones, has since taken to her Instagram Story to thank the actor for the lovely tribute, writing: "Wow a special message to our Indy Llew from Maui himself. @therock this means so much! Every night before bed Indy asks daddy to sing 'you're welcome'."
The Rock came across the young girl after a friend sent him a video his mom posted of her singing along with Alessia Cara's rendition of 'How Far I'll Go'.
As Indy was born with Down Syndrome, she has a greater risk of developing diseases such as leukemia.
The little girl has battled myelodysplastic syndrome, a rare blood cancer, at various points in her short life and is currently fighting leukemia, her mother revealed in an Instagram post last month.
We wish young Indy all the health, strength, and happiness in her recovery!
