Anna's Mom & Ex in Separate Biz

Anna Nicole Smith's ex and self-professed babydaddy to Smith's 5-month old Dannielynn, Larry Birkhead has filed a trademark application for the phrase, "Goodnight My Sweet Anna Baby" - the line he used to comfort his tragic ex-girlfriend Anna Nicole Smith as she fell asleep in his arms. -- He is seeking a trademark to cover movies, books, TV programs, electronic media and stage plays.

-- On the same front but a different note: Anna Nicole Smith's estranged mother Virgie Arthur has been summoned to court in the Bahamas for allegedly refusing to pay her legal bills. Attorney Jamal Davis claims he helped Arthur make sure her granddaughter Dannielynn didn't leave the Bahamas, where she was born, while the matter of paternity played out in court.

Davis says his law firm helped Arthur obtain an order to ensure Dannielynn was not taken outside of the Bahamas. He told Entertainment Tonight, "We represented her to the best of our abilities. We managed to avoid the child being removed from the Bahamas up until the point of time that we stopped representing her and we haven't received payment for our time and devotion spent on this matter.”

"We're just exercising our right as any creditor would do to recover our fees. It's unfortunate we have to take this route."
