A high-flying Valley Girl makes it big in Hollywood. Her beauty-pageant laurels led to TV commercials and a stint with the Embraceable Ewes (now known as the L.A. Rams cheerleaders). Next came several seasons as “clumsy Cindy” on the hit sitcom Three’s Company. Next came a role in Tank, then Dallas. Now comes Jenilee Harrison, 27, currently successful, sensational, happy—and all on her own terms.
