Justin Bieber ‘Shut Himself Off From the World’ After Diddy’s Arrest: ‘People Are Genuinely Worried’

Justin Bieber is on the verge of a total collapse as he faces the shattering possibility that sordid details about his relationship with Sean “Diddy” Combs will soon be exposed for all the world to see, sources exclusively tell In Touch.

Insiders close to the 30-year-old “Stay” singer say he’s “shut himself off from the world” as he wrestles with his disturbing past, when he was a fresh-faced 15-year-old trying to impress a music industry mogul whose alleged degenerate ways are only now coming to light.

“No one knows what’s going on with Justin,” says a member of his inner circle. “It’s like he’s fallen off the map since Diddy’s arrest and all the sick details coming out. People are genuinely worried about him.”
