Brown was in court Friday for an altercation last October, during which he allegedly punched and broke the nose of a man trying to take his picture. After the singer admitted he violated his probation, the judge sentenced him to four months in jail. Initially, he was sentenced to a year, but the judge gave him credit for nearly eight months of time served.
In March, Brown, 24, was ordered to stay in jail after being kicked out of his court-mandated rehab for violating internal rules.
Brown still faces a misdemeanor assault charge and was ordered to stay on probation and complete the remainder of his 1,000 hours of community labor after he leaves jail. According to TMZ.com, Brown could be released in as little as six days.
