Democratic presidential front-runner John Kerry can't seem to put that knotty Botox issue to rest.

Two prominent New York plastic surgeons - after examining "before" and "after" photos posted on the Drudge Report - told Lowdown yesterday that Kerry exhibits all the signs of a Botox injection.

"Not only is it Botox, but it's classic bad Botox," said Dr. Michael Kane, a surgeon in private practice.

"His forehead is just way too smooth. It looks weird. It's a bizarre appearance that he's got not a wrinkle. That doesn't happen to 60-year-olds."

Dr. Gerald Ember, an attending plastic surgeon at New York Presbyterian Hospital, agreed.

"The pictures ... show a marked absence of the horizontal lines of the forehead and wrinkles between the eyes. Only Botox or a forehead lift would do this," he said. "And I say good for him!"
