Singer Chris Brown issued an apology Sunday, one week after being booked in Los Angeles for allegedly assaulting his girlfriend, singer Rihanna.

However, Brown also said in a statement issued by a publicist that much of what has been reported about the alleged assault "is wrong," the Los Angeles Times reported Sunday.

Citing sources familiar with the investigation, the Times has reported that Brown, 19, and Rihanna, 20, got into an altercation early Feb. 8 after attending a Grammy Awards party in Beverly Hills, Calif. Both performers canceled appearances on the Grammy telecast that night.

Brown was booked on suspicion of making criminal threats and was released on $50,000 bail. Police have not officially identified his alleged victim and prosecutors have not filed charges against him.

"Words cannot begin to express how sorry and saddened I am over what transpired," Brown said in the statement issued Sunday. "I am seeking the counseling of my pastor, my mother and other loved ones, and I am committed, with God's help, to emerging a better person."

Brown said he was unable to talk more about the matter "until the legal issues are resolved." He also said he has not "written any messages or made any posts to Facebook, on blogs or anyplace else" about the incident, calling such posts written under his name fraudulent.

"Much of what has been speculated or reported on blogs and/or reported in the media is wrong," he said.
