LOS ANGELES (Reuters) - Bruce Willis and Demi Moore`s former nanny sued the Hollywood super-couple on Monday, claiming she was "shamelessly exploited and abused" while caring for their three children. But a lawyer for Willis and Moore said the suit by Kim Tannahill was without merit and filed by Tannahill only because she was sued first by the movie star couple. Tannahill, who began working for the family in March 1994, claims in her lawsuit that she was denied a social life and unable to see her boyfriend during her employment. The complaint says Willis and Moore "shamelessly exploited and abused plaintiff through fraud, deceit, oppression, intimidation, threats and force." Tannahill also claims she was "literally whisked away and required to engage in extensive traveling throughout the United States and the world." Martin Singer, an attorney for the couple, said the complaint amounted to a legal defense. "This is just a response to the suit Bruce and Demi filed against her in Idaho last week," he said. "A number of current and ex-employees will confirm that these allegations made by Ms. Tannahill are without merit." Singer said the actors sued Tannahill last week for alleged misappropriation of funds and defamation. Meanwhile, Willis, star of the "Die Hard" action movies, and Moore, who appeared on the soap opera "General Hospital" before the 1985 film "St. Elmo`s Fire" made her a household name, are also embroiled in a lawsuit against the Star tabloid. A Los Angeles judge last month refused to dismiss the $5 million libel suit against the Star for reporting that their marriage was on the rocks.
