Charlie Sheen To Save His Kids Following Brooke's Drug Bust?

Sources close to the couple tell TMZ, Brooke had custody of the 2-year-old twins the night of her arrest -- leaving them in the care of a nanny while she went out clubbing.

Brooke and the kids are currently on their way back from Aspen now -- but we're told, Charlie plans to take care of them as soon as they're home ... and Brooke's parents will help.

According to sources, Brooke's going to take some time for herself while she tries to "get better."
