Here's yet another reason to love Justin Timberlake: The singer recently made an 8-year-old boy's birthday unforgettable by halting his San Jose, California, concert to serenade him. In a YouTube post, Julian Delan's parents explain that their son has autism and they were worried other concert-goers would be upset over his "obsessions, his volume, his repetitiveness, his clumsiness." Instead, they helped the family capture Justin's attention and sang along as the pop superstar launched into a rendition of "Happy Birthday." Delan's mom has since shared a photo of her excited kid's face on Instagram, along with the caption, "We love you, Julian AND we love YOU Justin Timberlake !!! Thank you for making his birthday SO special!!!"
