Dr. Arnold Klein might have done some work on Michael Jackson, but so-called King of Collagen swears he didn't off the King of Pop.

And he's got a brand-new lawsuit to back him up.

Klein has sued a fellow physician for slander, claiming Dr. Steven Hoefflin passed himself off as spokesman for Katherine Jackson and made comments to Britain's Sun tabloid that opened up Klein to "contempt, ridicule and shame" and caused him to be "shunned and avoided and have injured his reputation as a person."

The suit, filed Monday in Los Angeles, claims Hoefflin linked Klein to Dr. Conrad Murray, the cardiologist who was the last to see Michael alive. The tab reported that Murray called Klein in the moments after Michael died because the dermatologist had schooled Murray on how to administer the powerful anesthetic propofol.

The coroner has ruled Jackson's death a homicide from an overdose of propofol, but no charges have been filed. Klein's lawyer has previously said the dermatologist has been "fully cooperative" with the investigation.

Klein's no fan of rumors. But one that won't go away is whether he's the father of Michael's children. Get the latest scoop here.
