Brooke Mueller is getting along much better with Charlie Sheen these days.
But the troubled celebrity is still fighting mad, aiming her anger at a treatment facility where she spent time in March of 2010.
Mueller has filed a lawsuit against The Canyon rehab facility in Malibu because she believes staff members there leaked confidential medical information to the press.
It is true that Brooke's patient admissions forms were submitted to websites such as TMZ last spring, though that celebrity gossip outlet did not publish the documents.
Mueller is suing for undisclosed damages because she believes her privacy was violated.
