Charlie Sheen -- I'm GLAD My Twins are with Denise Richards

Charlie Sheen SUPPORTS the decision to remove his twin boys from the custody of their mother Brooke Mueller ... Sheen's rep tells TMZ.

"Charlie supports the actions of the Department of Children and Family Services," his rep tells TMZ. "He knows Max and Bob are safe and in a stable, loving environment with Denise and the boys' sisters."

As we previously reported, Sheen's 4-year-old twins -- Bob and Max -- were taken Thursday night after the L.A. County D.C.F.S. decided Mueller's home was an "unsafe environment" due to her suspected drug use.
