Underaged in clubs, the process ?¿

I'm genuinely wanting to see if anyone has insider info on this. Like, maybe I sound dumb lol but.... what is it? Does she just have a super good fake ID? Would she pay the bouncers extra to let her in? Do they not care bc she gives them recognition from her following? Which one ??

I mean, she's clearly a known name, she posted everywhere a few months ago she only JUST turned 20.

Just curious 🙈

Edit: I am from Toronto so it's rare anyone who has a name for themselves is under the legal age here of 19 so that's why I'm clueless on how it works in the states lol
