A video of one of their young fans has surfaced from the event and it's beyond adorable, as the little boy approaches the guys and eventually joins them on stage to sing a bit of the 1D tune "Live While We're Young."
They really let him take the lead (after Liam chants "Ronnie" to get him pumped up) and just join in as supporting backup singers here and there.
When Ronnie's done, he runs away, but they call him back to share a handshake with each of the guys. Job well done, Ronnie - if the boys ever need a new member, we're pretty sure you're top of the list!
