Big Sean Explains Why He Gave Justin Bieber His Pinky Ring

'It's really what bosses do — we give each other gifts,' Sean tells MTV News.

HOLLYWOOD HILLS, California — With friends like Big Sean, who needs jewelers? After Justin Bieber tapped Sean to ride alongside him on "As Long as You Love Me," the new single from Believe, the G.O.O.D. Music rapper gifted JB with a pretty cool piece of bling as a token of gratitude.

"After he put me on his album and introduced me to a lot of his fans, I felt like, 'Yo, man, just to show my appreciation,' I gave him the Rolex ring," Sean explained to MTV News on Saturday at a party for his manager, Kevin Liles. "It ain't no thing; it's really what bosses do — we give each other gifts.

"It was the first ring I bought as soon as I started finally making money," Sean continued. "I got it and the first time I worked with Bieber, I came to the studio and he just loved this pinky ring I had on."

When the two stars appeared on the "Today" show together in June, the Detroit lyricist took the opportunity to salute Justin. And Bieber's manager, Scooter Braun, was on hand to witness the exchange. Last month, Braun recalled the conversation between Sean and Justin to MTV News: "[Big Sean] said, 'I know you said you liked [my ring], and I want to say thank you for involving me in the process and being a part of this, and I want you to have the ring.' And he took it off, and Justin put it on and it was a real genuine moment. They're friends."

For the "Dance (A$$)" rapper, working with Bieber also allowed him to display his versatility. And although he's known for some pretty suggestive raps, Sean was able to lay a fitting verse on the Darkchild-produced pop hit.

"It's tight that I can be a person that's so diverse that I can do both of those [kinds of songs] and it's not reaching," he told us. "I'm still me ... and I didn't compromise anything for Bieber. You know, I just didn't curse, which is easy. I don't have to curse every day."
