A picture of Houston in her coffin was printed on the cover of the magazine, and Ciara is horrified the photograph was even taken.
In a post on her Twitter.com page, she writes, "It is terrible that someone would take a photo of someone's body at rest & sell it to a magazine!!! just terrible!"
Houston was found dead in the bathtub of her Los Angeles hotel suite on 11 February (12) and was remembered by family and celebrity pals during an emotional four-hour memorial service on Saturday (18Feb12). She was laid to rest the following day (19Feb12).
