Alicia Etheridge, who wed Brown in June, told Radar Online that her husband is currently undergoing treatment.
"He's doing great," she said.
Elsewhere, a source told TMZ that Brown "decided that he needed help and wants to make the best out of the rest of his life for his children's sake".
Etheridge did not confirm what Brown is seeking treatment for, but he is believed to be receiving help with alcohol addiction.
Brown, who has previously spoken about his addiction issues, is currently serving three years' probation after being arrested for DUI in March.
