Diddy, 40, boasted of getting “buck fool crazy” with teenage Justin Bieber in this video, documenting the pair’s 48 hours together.

A teenage Justin Bieber documented a weekend spent with P Diddy in a YouTube video that remains on his official channel, 15 years later.

The video is garnering new attention online as Diddy sits behind bars, following his recent arrest on sex trafficking charges, and amid fresh speculation about his extreme, celebrity-filled parties.

At the time the video was published on Bieber’s YouTube channel, on November 10, 2009, Diddy had just marked his 40th birthday. Bieber was just 15 and still a rising star, a week away from releasing his debut EP.

The two-minute clip shows Diddy presenting the teenager with the gift of a luxury car.

“As soon as you turn 16, Imma let you rock this every time you want,” he says, presenting Bieber with the extravagant gift.

“When you’re 16, you’re good to go,” he tells the young singer, licking his lips. “When you’re 18, you get the house. You get the mansion.”

The rapper then addresses the camera, telling fans Bieber is about to embark upon “48 hours with Diddy.”

“Where we’re hanging out and what we’re doing, we can’t really disclose, but it’s definitely a 15-year-old’s dream. I have been given custody of him,” he claims.

“He’s signed to Usher – I had legal guardianship of Usher when he did his first album. I don’t really have legal guardianship of him, but for the next 48 hours he’s with me. And we’re gonna go buck fool crazy,” he continues.

Diddy then asks Bieber what he wanted to do over the next 48 hours.

“Let’s just get some girls, let’s go hang out with some girls,” the teen singer suggests.

Forty-year-old Diddy tells the camera he and Bieber, aged 15 at the time, are going to get ‘buck fool crazy’ together.

“A man after my heart – that’s what I’m talkin’ bout,” says Diddy, as the pair shake hands and walk off camera.

The 14-year-old video has garnered fresh attention in recent months due to the ever-growing allegations against Diddy.

“This has aged horribly,” reads one top-rated recent comment on YouTube.

“The fact this is out in the open for 14 years and nobody questioned it until now is crazy,” another person commented.

“The blood-chilling dread of not knowing what occurred after the camera stopped recording,” said another.

“Forty-eight hours with Diddy sounds like a horror movie,” another offered.

In fact, Bieber’s former mentor Usher said as much in a recently resurfaced interview, where he spoke about living with Diddy when he was a teen star, working on his debut album in the early 90s.

Usher was just 14 when he moved in with Diddy, then in his mid-20s, for a whole year.

“I went there to see the lifestyle, and I saw it,” Usher revealed in a 2016 interview with The Howard Stern Show.

New dad Justin is in a ‘happy bubble’ with wife Hailey.

“And it was … But I don’t know if I could indulge and understand what I was even looking at. It was pretty wild. It was crazy.”

As the hosts probed him for more details, Usher offered that there “were very curious things taking place, and I didn’t necessarily understand it.”

It’s been reported this week that Bieber, who recently became a father for the first time with wife Hailey, has no intention of wading into the media frenzy surrounding Diddy’s sex trafficking and sexual assault lawsuits.

“He’s aware of Diddy’s arrest and all the allegations,” a source told People.

“It’s not anything that he wants to focus on, though,” the source continued, explaining that now-30-year-old Bieber has been in a “happy bubble” since the birth of son Jack.
