Brooke Mueller's Brother Wins Guardianship of Charlie Sheen Twins

There has been a changing of the guard ... Brooke Mueller's brother, Scott, has just gone to court and won temporary guardianship of Brooke and Charlie Sheen's twins Bob and Max ... TMZ has learned.

As TMZ first reported ... Denise Richards -- who had temporary guardianship -- made it clear to the L.A. County Dept. of Children and Family Services during a meeting Thursday -- she could no longer handle Bob and Max because they were violent toward her daughters.

We've learned DCFS has signed off on Scott becoming guardian. We're told he will get the children tonight.
