Simpson a Heckled Hen at First Country Gig

Jessica Simpson had her country music debut at Country Thunder in Wisc. last night -- and walked out to a mix of cheers and boos. Kenosha News reported a number of scathing reviews from audience members such as, "It's crap, she doesn't belong here," "She's not good enough to be here," and "She's an embarrassment to country music."
