After drug rumors surfaced last month, Brooke checked into Two Dreams Outer Banks rehab facility in North Carolina, though her rep claims she was there to recuperate from pneumonia and emergency oral surgery.

Now it's being reported that Brooke checked into The Canyon treatment center in Malibu on February 9, just one day after Charlie was charged with felony menacing, misdemeanor 3rd degree assault and misdemeanor criminal mischief for their Christmas day scuffle.
