Phil Spector arrives at a Los Angeles area court minutes before the jury found him guilty of second degree murder for the 2003 death of Lana Clarkson.

Phil Spector had his teeth knocked out in a vicious jailyard brawl, it has been claimed.

The music legend got into a fight with a fellow inmate at the state prison in Corcoran, California, where he facing possible life imprisonment for murdering actress Lana Clarkson in 2003.

"Phil has quite a mouth on him," longtime pal Steven Escobar told a US newspaper. "Not everyone understands his humour. He said the wrong thing to the wrong inmate in the yard."

Spector, 70, is said to have suffered a bruised nose and a black eye as well as losing his teeth in the assault last November.

"He mouthed off to a big guy, who punched him," another source said.

"At first, Phil said he fell down a flight of stairs," says Escobar. "Later, he told family and friends what really happened."

A spokesman for Spector's wife, Rachelle, initially said: "There are still safety concerns. We don't want the people who put him in this position to retaliate."

But according to the New York Daily News, she later changed her story, saying: "Phil was not assaulted. Absolutely not."

Lt. Stephen Smith said: "We have no reports that he was involved in any altercations."

Spector was convicted in April 2009 of second-degree murder after a five-month retrial and more than 30 hours of jury deliberations. He was also found guilty of the lesser charge of using a firearm in committing a crime.
