Fonzworth Bentley spoke to The FADER about the creation of Kanye West's song "Ultralight Beam" off The Life of Pablo. During his detailed recollection of the recording process, Bentley revealed that Justin Bieber laced some vocals for the song.

Bentley explained that his connection with songwriter and producer Poo Bear helped bring Justin Bieber into the creative process.

"I called Poo Bear, who's from College Park and wrote a lot of Justin Bieber's album," Bentley said. "And he was with Justin at the time. I'm from Atlanta, Poo Bear is from Atlanta -- so Poo Bear comes up and catches the vibe. Justin hops on the phone and is like, 'Tell Yeezy whatever he needs I got it.' So Justin comes through and we vibed on that. And then Ye went right in. Ye was like, 'Let's all catch a freestyle."

As Bentley continued to describe the recording of "Ultralight Beam," he stated that Bieber sang an acapella during his time in the studio.

"In his freestyle he said, 'This is an ultralight beam." Bentley recalled. "He sings that and was singing the melody. Then Chance catches the vibe. A lot of what ended up in his verse was from this freestyle—as far as his patterns and some of the words. There weren't that many words, more so vibes and patterns. Then Justin got on the mic and sang some acapella. It was free flow. It was creativity. It was about 8 in the morning at this point. Ye had a bed set up at the studio and so he would usually take a nap for an hour or an hour-and-a-half, go to the gym, and then come right out."

As fans now know, Justin Bieber did not end up on "Ultralight Beam." But with the fluid status of The Life of Pablo's tracks, it is possible that a version of the song with Bieber's vocals could eventually be released.
