Niall Horan and Liam Payne had a mini 1D reunion on Friday night (June 23), when the two boy banders-gone-solo ran into one another backstage in Indianapolis, Indiana.

Appearing at local radio station WZPL ZPL's Birthday Bash concert, the two pop stars found each other backstage, where they proceeded to film their exciting, impromptu reunion.

"Look who I found!" Payne teases cheerfully in a clip posted to his Instagram, while Horan laughs, responding with a happy "What's up!?"
