In a revelation that has sent shockwaves through the entertainment industry, the just-published Ed McMahon autobiography, Heeeeeeeeeeeere's Ed, disclosed that the veteran Tonight Show emcee slept with seven separate women over the course of his long career. 'Frankly, a lot of people in Hollywood were stunned to learn this number,' said gossip columnist Liz Smith on Monday. 'Think about itthat would mean he had sex with one woman every six to nine years.' According to the book, McMahon's conquests include a woman he met overseas while serving in the Marines, a woman he dated for two years before she broke up with him, three other women he dated for five years before they broke up with him, and two of his three wives.
