Justin Timberlake has love for the kids.

According to Billboard, JT sang "Happy Birthday" to a young boy with autism at a recent concert during the pop star's latest tour.

Marika Rosenthal Delan granted her son Julian's wish of going to see Timberlake in concert for his 8th birthday but they had no idea what would happen once they got to the actual concert.

At the show, an excited Julian rocking fedora and JT-branded bow tie for the occasion chanted, "It's my birthday!! This is my present! This is my present! I I Love You JT!"

In a post on The Manifest Station, Delan wrote she feared that her son's singing and yelling might annoy the "model-esque girls" sitting next to them but that was far from the case.

Delan says before they knew it, the surrounding concert-goers had helped get Timberlake's attention on stage prompting him to serenade his young fan.

"It took us over an hour just to get outside the arena whilst Julian was high-fiving and fist-bumping everyone that stopped him," Julian's mother wrote. "Thank you for showing me I was wrong about what the world would do when they saw my son. Thank you for seeing him and not just his disability."

Watch Julian's reaction below.

Last month, Timberlake surprised a lucky fan named Robbie Twible with a limo ride and front row tickets to his New York City show.

Twelve-year-old Robbie suffers from a condition called epidermolysis bullosa, a skin disease that causes painful blistering all over his body. He was reportedly still recovering from a recent surgery at the time of his surprise.

When asked why he idolizes Timberlake, Robbie said the singer has talent and a good heart.

Very true indeed.
