Anna Nicole Smith was ordered yesterday to bring her 3-month-old daughter to California to allow for paternity tests sought by Larry Birkhead, Smith's ex-boyfriend. According to Birkhead's rep, an L.A. Superior Court ruled that Anna Nicole and daughter Dannielynn were ordered to submit to paternity testing, which Birkhead believes will prove conclusively that he, not lawyer-boyfriend Howard K. Stern, is the father. "Christmas has come early," said Birkhead, "and I thank God that I will soon have the opportunity to prove that I am the father ... and eventually hold her in my arms." Neither Smith's attorney nor a Superior Court spokeswoman would confirm or deny the ruling.
