Justin Bieber has not focused on his old pal Sean “Diddy” Combs’ sex trafficking arrest after welcoming his son, Jack Blues, with wife Hailey Bieber.

“He’s aware of Diddy’s arrest and all the allegations,” an insider told People on Sunday. “It’s not anything that he wants to focus on, though.”

The source explained that the “Baby” crooner has stayed busy “in a happy bubble since baby Jack was born” last month.

“He just wants to focus on being a great dad and husband,” the insider continued.

Justin, 30, and Hailey, 27, who wed in 2018, have gushed over being parents to their baby boy via Instagram since his arrival in August.

The model showed off a new diamond “mom” ring and her bundle of joy’s tiny feet, while the singer has flaunted his “Papa Bear” mug.

Combs, meanwhile, was arrested at the Park Hyatt New York City on Sept. 16 after “voluntarily” coming to the Big Apple “in anticipation of the charges,” a source told Page Six.

The disgraced rapper, 54, is currently at the Metropolitan Detention Center in Brooklyn.

He was charged with sex trafficking, racketeering conspiracy, transportation to engage in prostitution and fraud.

Per a grand jury indictment obtained by Page Six, the Bad Boy Records founder was also accused of “creating a criminal enterprise” with members who participated in “sex trafficking, forced labor, kidnapping, arson, bribery and obstruction of justice.”

According to the documents, more than 1,000 bottles of lubricant, drugs and three AR-15s were found in Combs’ Los Angeles and Miami estates when they were raided in March.

The “I’ll Be Missing You” emcee maintained his innocence and pleaded not guilty to the charges.

Since the sex trafficking raids at Combs’ mansion, “creepy” clips of a young Justin with Combs have resurfaced.

One video of the then-15-year-old “Peaches” singer showed him standing alongside Combs as they bragged about the unspeakable antics they would be doing that day.

“Where we hanging out and what we doing, we can’t really disclose, but it’s definitely a 15-year-old’s dream,” the disgraced rap mogul said.

Combs explained Justin was signed with Usher, whom he had “legal guardianship” of in the early ’90s when he produced the “Yeah!” crooner’s self-titled first album.

“I don’t have legal guardianship of him [Bieber], but for the next 48 hours, he’s with me,” Combs said. “We gonna go full buck full crazy.”

“Going crazy,” Justin added.

Days later, another “disturbing” video showed Combs questioning why Justin distanced himself from him, as the “STAY” singer’s career began to skyrocket.

“Starting to act different, huh?” Combs said. “You haven’t been calling me and hanging out the way we used to hang out.”

“I mean, you tried to get in contact with me throughout all my [projects] and what not — but you never got my number,” the dad of one responded while stumbling on his words.
