Chris Brown and Frank (no relation to Billy) Ocean were (allegedly) involved in a fight last night.

Sources close to/currently facilitating Brown claim Frank started the dispute when he blocked the 23-year-old singer from leaving Westlake Recording Studios in Los Angeles, where he was listening to one of the artists he represents.

Insiders whispering furiously to TMZ claim Frank said: "This is my studio, this is my parking spot." What were you expecting, a debate about life, the universe and everything that just got out of hand?

Chris - who is still on probation for viciously assaulting on/off/on/off girlfriend Rihanna in 2009 - is said to have attempted to shake Frank's hand, but sources close to the 'Beautiful People' singer claim one of Frank's associates then attacked Chris. One of Chris' friends is then said to have hit Frank's friend in retaliation before Chris then pushed Frank away as he approached him and the pair started fighting.

The 25-year-old singer/songwriter has taken to his Twitter account to claim he was "jumped by Chris" and now has a hurty hand which could hamper his performance at the Grammy Awards next month. He posted: "got jumped by chris and a couple guys. lol. i only wish everest was there. cut my finger now I can't play w two hands at the grammys. (sic)"

Police arrived at the scene and spoke to Frank, but Chris was not there. The officers have now cleared the scene without making any arrests and it is thought nobody wants to press charges - because we've all now heard of Frank Ocean and have been made aware that he's playing the Grammys next month.

In July 2012, Chris denied being homophobic about Frank - who came out as gay in a blog post last year - when asked his opinion about the Pyramids hitmaker.
