Niall Horan and Katy Perry have quite the adorable past. As any One Direction fan knows, Katy was the guest judge on the X Factor panel the day Niall auditioned and she ended up being the swing vote that decided if he would be able to make it to the next round. And she said "yes" to the little blonde singer, letting him through and basically changing his life in that instance.
He made a promise he wouldn't let her down too.
AND HE SURE DIDN'T. Niall went on to become a member of one of the biggest boy bands in recent history and he's never forgotten what Katy did for him. They even shared a precious little smooch at the 2012 MTV Video Music Awards.
Fast forward to today, and Niall is now a thriving solo artist. He just so happened to run into his longtime bud Katy at Capitol Records' Hollywood Gala last night too and they snapped some precious pics together of course, proving their bond is unbreakable.
