WWBD — What Would Bieber Do — if faced with the opportunity to save one person and let the other drown when the two people are his girlfriend Selena Gomez and his mentor Usher? Ooh, that’s a toughie. The question was actually posed to the ‘Boyfriend’ signer during an interview with Big Boy on his radio show.

Big Boy presented the scenario that would ultimately test The Biebs’ loyalty, saying, “You’re on a raft in the middle of the ocean and you look in the ocean and there’s two people in the ocean and you can only bring up one person and the other person will drown. You see Usher in the water and you see Selena Gomez in the water. Who do you pull up and who do you let drown?”

At first, The Biebs was diplomatic in his choice, offering to throw himself under the bus, uh, raft. But that was not an option. It’s either Selena or Usher. The Biebs thought about the dilemma and then offered his decision, saying, “I mean, Usher’s a grown man, he can get up on the raft by himself, so I’ll help Selena.”

Right answer, JB, right answer. We’re sure Usher would have told you to say the same thing.
