Brooke Mueller will check into rehab again.

The former wife of Charlie Sheen was allegedly placed under an involuntary psychiatric hold at the UCLA Medical Center last week before checking out on Friday but is once again receiving treatment at the facility and is planning to get help for her ''prescription drug abuse''.

Her representative told the New York Daily News: ''Brooke will be [at UCLA Medical Center] for several more days, and will likely transition directly into a residential treatment facility to get help for prescription drug abuse.''

The 35-year-old socialite's four-year-old twins with Charlie, Max and Bob, are currently staying with his other ex-wife Denise Richards after she secured temporary custody of them last week.

A source said: ''Brooke didn't have a say in this. They came in, assessed the situation, asked Denise to take the boys, and Brooke agreed. Brooke is very comfortable with this and very grateful to Denise for taking this on. There's no ill will there.''

Brooke - who has been in rehab 19 times - was previously said to be happy that Denise, who has daughters Sam, nine, and Lola, seven, with the 'Anger Management' star, as well as adopted daughter Eloise, two, is caring for her boys as she thinks she is a great parent.
