Aspenite George Gradow, the husband of fomer Playboy Bunny Barbi Benton, pleaded guilty in federal court in Denver Wednesday to obstructing a federal tax investigation:

The 65-year-old husband of ex-Playboy bunny Barbi Benton and father of two teenaged children faces up to 18 months in prison under his plea agreement…..”We were going through an audit. I had certain terms in documents changed,” Gradow said. “I was stupid, your honor. I thought that I could get away with it.” [Judge]Daniel asked him why he did it. “Simply to deceive the Internal Revenue Service,” Gradow said.

Gradow and Benton own and reside in one of the most expensive residences in Aspen. Named “Copper Palace,” the home has more than 25,000 square feet and is worth $25 million.
