The 47-year-old "My Prerogative" singer has agreed to seek help for substance abuse issues at the urging of his pregnant wife and manager Alicia Etheredge, reported New York Daily News.
"Bob is in rehab," a source said.
The insider added that the 47-year-old star was seeing help in California for cocaine and alcohol problems.
Brown's attorney denied that was the case, though refused to answer when asked directly if his client was being treated for substance abuse, saying only that he will be appearing at an upcoming concert on March 4.
