Some of you might not know this, but Katy Perry is partially responsible for the creation of One Direction. The songstress was one of the guest judges when Niall Horan auditioned for X Factor back in 2010, and she gave him a yes after being impressed by his Irish charm (Cheryl Cole said no). Niall's probably had a crush on her ever since, because earlier tonight he officially proposed to the Prism pop tart following her UK X Factor performance of "Roar."
I love you @katyperry ! Thank you! Ps . Will u marry me?

Katy sounded off-key and the masked suitcase-wielding backup dancers were a bit of place, but she did bend over and show off her famous double D's a lot, and what 20-year-old wouldn't want to marry her after seeing that?
