Lilly from Malden was in for quite the treat when she stopped by Kiss 108 for a live in-studio performance!
When Brady, Chance, Drew, Sergio, and Michael of In Real Life found out it was Lilly's 18th birthday, they broke out into stunning five-part harmony to serenade the glowing young fan with a stunning rendition of "Happy Birthday."
In Real Life came together on ABC's reality show Boy Band in 2017. Check out their impromptu performance below!
