Like Katy Perry walking outside with a face mask, Mitchell DGAF about looking pretty on a flight. "I never, ever wear makeup on a plane," she explained. "I learned that one from all the times I would wear some trying to look cute on a flight, but then I'd land and I'd have a new buddy on my face. There's not the cleanest air on the plane, your skin is dehydrated, it's going through all these changes — it's a lot, so I take off every single piece of makeup and just go barefaced.
