Justin Bieber Catches a Bite Before His Flight

When you're Justin Bieber, you're always on the go. But nutrition — and fast food — is a necessary part of the traveling life! The Biebs picked up some In-N-Out burger before catching a flight at LAX in L.A. on Monday, accompanied by his assistant, and of course, a very burly bodyguard. The teen sensation gave photographers his goofiest smile on his way to the plane.
