She posted an Instagram video of the fail, writing, "when u slip on confetti & almost die at madison square garden 😭😩😂."
Of course, we totally didn't even realize that she was faltering that much at the moment she says she almost-slipped. She really is a pro!
Despite her crazy experience, she couldn't stop gushing about how much fun she had during the event.
Girl didn't let a scary near-slip get her down!
