Justin Bieber is allegedly scared of Judge Judy Sheindlin. At least he was back in 2014 when they were neighbors.
During an interview with “Access Hollywood”, Judy said, quote, “He’s scared to death of me. There was a period of time before he grew up when he was foolish, and doing foolish things…
“I must have said something about it, and then I understood that he was paying the front door people to [let him know] when I was there, coming and going, so he wouldn’t have to bump into me.”

In an interview with CBS back in 2014 she said that he was making a fool of himself. If you remember back then, Justin wasn’t doing too great. He was arrested in Miami for drag racing in his Lamborghini . . . and he failed a sobriety test.
