​Just months ago, we were hearing news of Justin Bieber and Selena Gomez's ​split, as their efforts to rekindle their romance just weren't in the cards this time around. And apparently just a couple months time was enough for the Biebs to move on, and even ​get engaged! I'm not the only one who's finding this all crazy, right?

But nevertheless, this is the reality, and like most, I am happy for the newly engaged couple. They took their ​on-again, off-again fling from 2015-2016 and made it into something ​actually real.

Being the ultimate ​Justin Bieber stan Hailey was growing up, I was certain she'd say anything goes for the wedding, just to be marrying the man she not only loved as a fan, but now as a person too. However, it looks like there's one thing she's making clear is not allowed on their big day.

When Justin's road manager Ryan Good commented on the engagement news, he suggested something absolutely unacceptable by Hailey. "Grow the mustache back for the wedding," he wrote.

Hilariously, Hailey wrote back, “don’t u dare give him that idea you lunatic.”

All jokes aside, it seems like literally no one is a fan of Justin's 'stache, not even his fiancé. It's definitely time to retire that look forever, Biebs, 'cause you're about to be a married man, and you can't just be making major decisions like that by yourself anymore!
