The former actress is back living in the exclusive gated community and taking care of her twin boys with Charlie, Bob and Max, four, rather than her brother, Scott, who was appointed their guardian before Christmas.
A source told RadarOnline.com: ''Brooke has been living at the mansion in Mulholland Estates since before Christmas.
''The boys had been living at the house with their temporary guardian, Scott Mueller, but he hasn't been spotted at the house lately.
''He's been back at his house in Orange County [California] to be with his family. Brooke does have a nanny and a sober living companion also with her in the house. There just wasn't enough room at the condominium she had been living at for her staff.''
Brooke, 36, originally lost custody of the twins when she was placed on involuntary psychiatric hold at the UCLA Medical Center last year. She has since sought treatment for her drug dependency and is said to be on the road to recovery.
Another of Charlie's ex-wives, Denise Richards - who also lives in the same gated community - initially became guardian to the boys, but she had to give them over to Scott after they started to display violent tendencies toward her own children.
It is not known if Brooke's move back into her home has been sanctioned by the Los Angeles County Department of Children and Family Services, but the source added she is determined to win custody of them back, and is currently on course for that to happen by May.
