Officials have said that Mueller's home is an "unsafe environment" for children and handed them over to his ex-wife Denise Richards, reported the New York Daily News.
"It just wasn't a stable environment with different nannies coming in and out, and child protective services came in and did their thing, and this is the outcome. Brooke didn't have a say in this. They came in, assessed the situation, asked Denise to take the boys, and Brooke agreed.
Mueller has struggled with drug use for years going in and out of rehab facilities and according to reports she is now suspected to be using again which caused the children to be taken from her.
