Justin Bieber fired his longtime “assistant” years ago, our team has learned — this amid new reports claiming JB’s team recently began shrinking due to concerns about his well-being.
Sources with direct knowledge tells us … despite new reports suggesting Justin’s assistant quit recently — as Justin’s inner circle gets smaller — we’re told JB’s former estate manager, Mateo Caldas, was fired by the singer 5 years ago.

Our sources wouldn’t specify why Mateo was cut loose in September 2020, but clarified he was never Justin’s personal assistant — his sole responsibility was to oversee Justin’s Los Angeles estate.
Our sources stress allegations implying Mateo left his gig with the singer recently are “grossly untrue.”
The most recent rumors about a shake-up in Justin’s camp come amid ongoing tabloid fodder and social media speculation JB is using hard drugs.

As we reported … a rep for the Biebers told us last week that recurring drug narrative is absolutely not true. We’re told Justin is actually in one of the best places in his life. He’s focused on actively parenting his newborn son with his wife Hailey Bieber, and he’s been working on new music.
