Justin Bieber Co-Signs Diddy’s Album While Recording New Track

'Everybody, if you're anybody, you'll go get the album,' Bieber says of Last Train to Paris.

On Tuesday evening, MTV News was on hand when Justin Bieber was discovered laying down tracks at Diddy’s recording studio in New York City.

“In the studio getting creative,” he wrote. “Just got to show luv to my big bro @iamdiddy and his new album ‘Last Train to Paris.’ ”

Bieber’s manager, Scooter Braun, explained to us that the pop star had an idea for a song that he needed to “get off of his chest,” and that Diddy’s studio is like a second home for the teen superstar.

MTV News was spending the day with Diddy, who just released his Last Train to Paris album. Though the rap mogul hardly ever stops working himself, he jokingly complained about Bieber being too busy for him these days.

“Well, I mean, you try to get in contact with me through all my partners and whatnot, but you never really got my number, so you want my number?” the 16-year-old responded.

After an exchange of phone numbers, Diddy made Bieber an official member of Diddy-Dirty Money and gave him and Braun¬†the group’s official varsity jacket. “Go get the album. Everybody if you’re anybody you’ll go get the album,” Bieber said endorsing Last Train.

“It’s gonna be the greatest album you ever heard,” he later added. “Everybody’s on this album. Go get this album. We’re out.”

“I’ve missed the studio. Just making music,” Bieber later tweeted. “Made some great records tonight. Now en route to see my big bro @usherraymondiv.”

Bieber then went to take in Usher’s show at Madison Square Garden, later tweeting, “big bro @usherraymondiv killed it at MSG tonight. … I had to come thru and support #family.”
