LATEST: Zsa Zsa Gabor's husband PRINCE FREDERIC VON ANHALT has added a new twist to the paternity battle over late actress/model Anna Nicole Smith's baby daughter after stating he could be the child's father. Smith's ex-boyfriend LARRY BIRKHEAD and partner/attorney HOWARD K. STERN are fighting over paternity, both claiming to be baby DANNIELYNN's biological father, but now 59-year-old Anhalt suggests he, too, could be the baby's daddy. He tells the Associated Press he has had a decade-long affair with Smith, adding he'll file a paternity lawsuit if either Birkhead or Stern are granted custody of baby Dannielynn. The paternity issue will be resolved on 20 February (07), when a court-ordered DNA test on the five-month-old baby takes place in Los Angeles. At present, Stern is listed as the baby's father on her birth certificate, but Birkhead has been fighting to prove he's the father since late last year (06). Von Anhalt has been married to socialite and actress Gabor, 90, for over 20 years.
