KISS legend Gene Simmons has been slammed for comments he made last night as a guest judge during "Hair Metal Night" on hit competition TV show Dancing With the Stars. This week's episode featured pairs of contestants performing choreographed dance routines to some of the biggest and most popular hits of the hair metal era. The opening sequence even featured a cameo from Whitesnake guitarist Joel Hoekstra playing a smoking guitar to a cover of KISS' "Rock and Roll All Nite."
