As the world continues to get to know a new side of Charlie Sheen, where are his four young children in the midst of all this?
Authorities removed his twin boys, Max and Bob, nearly 2, from his care Tuesday night and returned them to their mother, Brooke Mueller, after she won a restraining order. Soon afterward, Sheen urged Mueller on NBC’s Today show to “tell me where our sons are.”
A source close to Mueller tells PEOPLE the boys are currently living in an L.A.-area rental apartment with her, along with Mueller’s mother Moira Fiore and a nanny while Fiore waits to complete a purchase on a condo.
