Justin Bieber is "more manly" now or something and he enjoys carrying himself in a manner that reflects that. So nothing says 'I'm an adult' more than acting like a spoiled rich kid in a sea of sycophants while in first class on an airplane. I'm serious, if you can afford to fly with an entourage in first class when you're a teenager, you're pretty much an effin' boss.

Justin was on a 12-hour flight from Australia to LA when Justin and his entourage started dropping a lot of four-letter word bombs.

A lady had the audacity to approach the Biebus and said: "stop yelling curse words and using that kind of language on a plane. It's not appropriate."

Because he's such a player gentleman, Justin quickly apologized.
