Bieber’s once-close relationship with Diddy is now under heavy scrutiny, with concerning videos re-emerging online.

Justin Bieber is trying to ignore the increasing rumors about his connection to Sean ‘Diddy’ Combs and focus on his role as a first-time father, but those close to him worry he is feeling more stressed by the growing pressure.

Combs, 54, was arrested in New York last week and charged with an indictment accusing him of years of coercion and abuse, using blackmail and violence to manipulate his victims.

Bieber’s once-close relationship with the disgraced rapper is now under heavy scrutiny, with concerning videos reemerging online showing a 15-year-old Bieber spending ’48 hours with Diddy’ and the two attending parties together.

Bieber, 30, who recently welcomed his son Jack with his wife Hailey, 27, has remained silent on the matter, but fans have expressed concerns over his seemingly ‘thin’ appearance.

Now, sources have informed DailyMail.com that the singer feels isolated in dealing with the revelations about Diddy, saying he is “sailing these waters alone.”

“Justin feels like there is no one that he can talk to that understands and, to be honest, he doesn’t even fully understand,” the insider explained. “He was a kid.”

The source also mentioned that this situation is happening while he is trying to be a good parent, despite not having had a strong role model in his own father, Jeremy Bieber.

“Justin is stressed right now,” the insider added. “He has a baby boy and is trying to be a good dad without any real example of what a good father looks like.”

Commenting on the singer’s fragile emotional state, the source continued: “He is sailing these waters alone and everyone fears that if Hailey shows any struggles with being a first-time mom, it will make things incredibly hard for Justin.”

“Diddy could not have happened at a worse time as he is trying to enjoy the happiness of becoming a father while dealing with this difficult situation.”
