Directioner Talia Winters' brother threw her phone on stage during their "One Way or Another" performance...and Harry caught it, taking the opportunity to get a little video footage.
A brief shot of Harry sticking his tongue out, some of the other lads' backs, and...well...dream come true time for young Talia.
She later tweeted: "@Harry_Styles thanks for taking a video on my phone at the concert Harry! Best night!"
No doubt Talia had some thanks for her dear brother, who thought to chuck the phone on stage.
The Harry fun begins at 2:18.
