The manager of Justin Bieber has opened up about an expensive piece of jewellery he was given recently and explained that the ring was given to him by a rapper.

The 'Boyfriend' hitmaker may be raking in the millions himself, but he was recently gifted a $30,000 ring by Big Sean to congratulate him on his fantastic success.

Scooter Braun, Bieber's manager, told MTV News that it was a great moment between the pair who have become great friends:

"When they first met, Sean has this ring. It was his first ring he ever bought, the first piece of jewelry when he got his record deal. He gave it to Justin [at the Today Show]."

"He said, 'I know you said you liked it, 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."

Last night (July 2), Bieber took to social networking site Twitter and told his fans that he's due to shoot a new music video this week:

"Feeling crappy. big week coming up. #AsLongAsYouLoveMe video shoot."
