I also find it amusing, and oh so classic Jonnyboy that he chose to take as his new surname the same as that of one of his biggest detractors, Kari Simpson.I suspect, if he legally changed his name, it has more to do with his need for employment than any legal case.
Most employers will at least do a Google on an applicant before hiring. "Jessica Yaniv" brings up thousands of hits that would keep an employer from hiring him. "Jessica Simpson" gets millions of celebrity hits that would cause this guy's history to be lost in the miasma.
I'm surprised he didn't go with Jessica Hamm, tbh.
