Brooke’s rep said in a statement, “As part of her ongoing treatment and as planned, she voluntarily checked herself into a rehab facility several weeks ago.”
Brooke relapsed and checked into a facility for treatment for crack cocaine addiction, Celebuzz, which broke the news, reported.
Brooke could end up in jail, as she is on probation following a drug arrest in December in Aspen, Colo.
A source tells Celebuzz, “she met up with Charlie again, partied for four days straight at his Mulholland Estate home and ultimately fell off the wagon.”
The Web site adds she missed spending Mother’s Day with her and Charlie’s three-year-old twins, Bob and Max, on May 13.
