April 18, 2006 -- LOS ANGELES - The former-wife of billionaire Kirk Kerkorian is suing a celebrity private investigator who allegedly wiretapped her during her child-support battle with her ex.

Former tennis pro Lisa Bonder Kerkorian filed suit in Los Angeles against gumshoe Anthony Pellicano, claiming invasion of privacy, emotional distress and that he violated federal wiretapping and eavesdropping laws.

AT&T was also named in the suit.

L.A. prosecutors have claimed Pellicano was paid $100,000 by Beverly Hills lawyer Terry Christensen to bug Bonder Kerkorian's phone in 2002.

Christensen, 65, is facing federal charges in connection with the scandal.

The suit claims that the billionaire's ex-wife was heard discussing the identity of her child's biological father and other matters with her lawyer that are protected by attorney-client privilege.

Pellicano bragged that the information he picked up from the wiretaps was "worth its weight in gold," according to court papers.

Meanwhile "Die Hard" director John McTiernan, another Pellicano client who had been indicted in the phone-tapping case, pleaded guilty yesterday to lying to federal agents.

McTiernan admitted that he had lied when he said that he had not asked Pellicano to wiretap producer Charles Roven, with whom he worked on the 2002 film "Rollerball."
