Justin Timberlake just proved – yet again – what a cool guy he is. After all, it’s not every day that a performer will interrupt their gig and get a packed stadium to sing “Happy Birthday” to an 8-year-old boy. Julian Delan, who was diagnosed with high-functioning autism in 2014, wanted nothing more for his birthday this year than to see JT in concert.

She thanked the group of young women in front of the family that night for getting Timberlake’s attention over the screaming crowd and letting Julian have his moment of glory.

"And at the perfect quiet moment, the group in front of us started yelling to get Justin's attention, because despite his loud volume, Julian's voice was not carrying. Only repeating," Julian's mom said. "And then before we knew what was happening, the group in front of us that had turned out to be so incredibly kind all night to our birthday boy, and these gorgeous girls who I was convinced would be totally annoyed by Julian, had captured Justin's attention."
