"He's scared to death of me," Judge Judy said of the now-28-year-old Grammy winner. "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 them know when I was there, coming and going, so he wouldn't have to bump into me," she added with a laugh.
TooFab has reached out to Bieber's reps for comment.
Judge Judy shared her thoughts about Bieber following his DUI arrest in 2014.
"Being a celebrity is a gift," she said to CBS Los Angeles at the time, per People. "You could either treat it reverently or you could make a fool out of yourself. And he's doing a very good job of making a fool out of himself."
"I think it's sad," she continued, adding, "And nobody's going to remember that he was a marginal singer. But they're going to remember a young kid who had a chance to have it all and who is blowing it by acting like a fool."
Meanwhile, also during her new interview with Access Hollywood, Judge Judy opened up about her future as a TV judge, explaining why she doesn't plan on saying goodbye anytime soon.
"If you find something that you're naturally good at, and can figure out a way to make a living [out of] it, you never work," said Judge Judy -- who was promoting "Judy Justice" Season 2 -- "I love what I do every day. I don't play golf. I don't play mahjong. I don't play tennis. There's nothing that I enjoy more than this."
"I've had a terrific run and I don't expect this to be over for a long time," she added.
