Sadly this is one most people didn't need a coroner's report to figure out, but we now "officially" know what killed Whitney Houston.

The LA county coroner's report says Houston drowned in a bathtub at the Beverly Hills hotel last month.

Her death stemmed from heart disease and using cocaine right before she slipped under the water in her tub.

But crack cocaine wasn't the only drug in Whitney’s body; weed, Xanax, a muscle relaxer, and Benadryl were also in her system.

Surprisingly, officials say those drugs did not contribute to her death and even more shocking there was no cocaine found in her hotel room.

Yeah, probably cause somebody removed it!

Houston's family says "we are sad to hear of the toxicology results, although we are glad to have closure."

Sad someone with so much talent, and every available resource, couldn't kick a habit that eventually took her life.
