Source: Whitney Houston Failed Medical Exam Before Death

There are new reports that have surfaced that reveal the late Whitney Houston failed a medical exam a few weeks before the iconic singer's untimely death.

Houston was trying to get a face lift, which would have been performed by a notable plastic surgeon in Beverly Hills, according to reports.

Dr. Marc Mani, a board-certified plastic surgeon, consulted with Houston, but ultimately refused to conduct the procedure following a failed medical clearance exam, a source told

Dr. Mani could not to confirm if Houston, who was found dead in the bathtub of her hotel room, had visited his clinic due to federal medical privacy laws.

There is wide speculation as to the exact cause of death, with results from the toxicology tests taking up to six weeks to be completed.

There are also unsubstantiated reports which have stated that sedatives were found in Houston's system. The claims state that the star had ingested sedatives such as benzodiazepines.

Dr. Mani did tell that with the recent high profile deaths of several celebrities he has come out against those who would give the medical profession a bad name.

"As a plastic surgeon who treats a lot of celebrities you have to be very strict about medical clearance … medical clearance includes a very thorough battery of tests including heart tests, lung tests, liver tests and other laboratory tests," said the physician.

He continued to state that "these situations make you aware of the need for a wakeup call to many physicians who are over-prescribing medications to celebrities to keep them on board. That shouldn't be the standard."

Dr. Mani said physicians should be held to a higher standard, noting that he feels "very strongly about celebrities' being overindulged by physicians, I treat a lot of them and care for them."

The Los Angeles County coroner's office has issued subpoenas for medical and pharmacy records from Houston's doctors and medical providers.
