(SHINee Fans) Did Key really steal Taemins first kiss?

Okay so I was reading comments and I keep seeing that Key really was Taemins first kiss. Is this true? They keep saying "I know it's true because I saw it" where the heck do you find this video or pic? The only video iv seen on a kiss (joke) was the one where taemin was being playfull during a lucifer performance. And that wasn't even a real kiss their faces just got close... So yeah if anyone knows where I can find this so called kiss let me know... Thank you(:
