Victoria Duffy, widow of Dennis Hopper, denies she’s already found another man. While in town last weekend with her 7-year-old daughter, Galen, to view Hopper’s artworks before they were auctioned at Christie’s, a source said Duffy was getting cozy at The Lion with Long Island-based private jet charter executive Eric Lang of Eastway Aviation. But both denied a romantic relationship. “We are really great old family friends,” Duffy told us. “We met in Vermont when I was 17 years old.”
