When Jessica Wigsmoen first met Napster cofounder Shawn Fanning at a party at Sean Parker's West Village party house, she didn't think it would end like this. "I lived in New York, I had a really good life," Wigsmoen told me by phone last week. "I met this guy who acted like prince charming." Now, she claims Fanning is denying child support for their 2-year-old daughter, Scarlett.
