SAN JOSE, Calif. (KGO) --
Justin Timberlake is known for making his concerts memorable for fans and that's exactly what happened to 8-year-old Julian Delan at a concert in San Jose earlier this week.
Julian has autism and his mother took him to see Timberlake for his birthday present. She was nervous to bring him thinking other concert-goers would react badly to his behavior. Instead, a group of women behind standing him noticed Julian and were somehow able to get Justin's attention.
Justin noticed and then launched into an impromptu serenade. "You know what Julian, this is for you," Justin said as he and some 20,000 fans sang "Happy Birthday" to Julian -- a moment he will likely never forget.
