NEW YORK - Liza Minnelli’s bodyguard claims the Oscar-winning actress made him have sex with her in order to keep his job, according to recently unsealed court documents. The allegations are detailed in M’Hammed Soumayah’s $100 million lawsuit against the entertainer. Minnelli’s lawyers did not return calls for comment Wednesday. But in a court document, one of her lawyers said Soumayah had “commenced this action in a quick sand of untruths and misstatements” and accused him of a “shakedown” of her client.
