The star has made just a handful of public appearances since allegations against Combs first emerged, and Hailey is said to be feeling like Justin's 'gatekeeper' amid the drama, an insider has revealed.
Justin, who welcomed son Jack with wife Hailey last summer, caused concern over his well-being when he suddenly unfollowed his wife on social media in January.
The hip-hop titan, who was once a close friend and mentor to Justin, is currently behind bars awaiting trial on charges of sex trafficking, abuse and racketeering - all of which Combs vehemently denies.
In his 2020 documentary, Justin Bieber: Seasons, he confessed: "There was a time where I was sipping Lean [codeine cough syrup and soda], I was popping pills, I was doing Molly [MDMA], you know, 'shrooms, everything.
Despite their close friendship, Justin's early career was tumultuous, with rumours that he was "thrown to the wolves" as he partied with Combs during his teen years.
