A shady Atlanta businesswoman armed with a gallon jug of silicone and syringes is offering to inject women seeking "J.Lo butts" in a Manhattan hotel room - an illegal and potentially lethal cosmetic treatment.

"I need to see your butt," Kimberly Smedley told a Post reporter posing as a customer last week in a suite at the Eastgate Tower Hotel on East 39th Street.

Smedley, a heavyset woman wearing camouflage pants and fake Ugg boots, then demanded $1,600 in cash to give nine injections to each cheek.

ALBANY, Ga. (AP)--The death of a transsexual who received injections of industrial-grade silicone illustrates the dangers of ``pumping,'' a thriving underground practice in motel rooms or apartments among men living as women. Authorities say 23-year-old Andre D. Jeter suffered convulsions and fell unconscious Dec. 10 after receiving injections in her hips and buttocks during a ``pumping party'' here. She died a month later.

Stephen Oneal Thomas, 31, was charged last week with murder and other offenses for allegedly administering the injections. Thomas' lawyer refused on Tuesday to comment.

One of Thomas' roommates, Nikkia Scott, and other drag queens have been getting illegal, back-room injections of silicone to give themselves some of the things nature denied them when they were born male--breasts, wider hips, more prominent cheekbones.

They know the risks are extreme, and still they do it.

``Anything you put in your body that don't belong there will hurt you in the long run,'' Scott said of her $6,000 worth of injections. ``But believe me, it has been worth it. It has been worth it.''

Scott and three others were also arrested in the case and charged with conspiracy and practicing medicine without a license. They were accused, among other things, of helping Thomas by recruiting patients at drag-queen beauty pageants.

The victim was a man living as a woman, as are all four defendants. While medical-grade silicone is implanted under the skin in sealed sacs to keep it from leaking, pumping involves injecting silicone straight into the body. And the silicone used is the stuff sold in hardware stores as a sealant. It is not sterile and can cause infections, particularly in the lungs.

The silicone is often mixed with paraffin, oil, even peanut butter, said Dallas Denny of the transgender support group Gender Education & Advocacy. In Jeter's case, it was probably mixed with baby oil, based on how it smelled to others who received the injections, said James Paulk, an investigator for the district attorney.

There was so much silicone in Jeter's body that when incisions were made during the autopsy, a clear, brownish liquid flowed out, Paulk said.

The scope of the phenomenon is unclear. The Centers for Disease Control and Prevention, the Food and Drug Administration and transgender groups said they do not keep track of the problem. But Paulk said a ``slew'' of people have been injured, including three or four in Montgomery, Ala., six or seven in Columbus, Ga., and a few in Jacksonville, Fla.

``The transgender society is a very tight-knit society. They don't like to give each other up because if you do, you get barred from the pageants,'' Paulk said.
