– Justin Bieber may be an international pop star, but he’s also a teenage boy—and lately, he’s been proving it. On a recent international flight, Biebs and his entourage reportedly started cussing, loudly, in first class. A mom of two (who should probably now be your hero) approached the group and, a source tells TMZ, asked Justin to “stop yelling curse words and using that kind of language on a plane. It’s not appropriate.” An embarrassed Bieber apologized, a friend says. But apparently he’s just as loud at home: On The View yesterday, celebrity couple Kristen Bell and Dax Shepard revealed that Justin recently moved into a house behind them, People reports. "The music and the parties and the paparazzi, I mean, it's like living in Lebanon now," Shepard said. Bell added, "In his defense, I will say we don't know the exact house the music is coming from. We just know since he moved in, the music has been blaring."
