The Dannielynn Hope Marshall Birkhead paternity case, a.k.a. Birkhead v. Marshall, centered on a child born September 7, 2006 to Vickie Lynn Marshall (better known as Anna Nicole Smith). The child was named Dannielynn, and was registered on her birth certificate as the daughter of Vickie Lynn Marshall (Smith) and her live-in partner Howard K. Stern. Larry Birkhead, Smith's former love interest and photographer, steadfastly maintained his contention that he was the baby's father and filed a lawsuit to challenge paternity after Smith had given birth.[1]
Besides Birkhead and Stern, bodyguard/actor Alexander Denk, Mark Hatten and Frédéric Prinz von Anhalt, among others, claimed to be the father of Smith's daughter, Dannielynn. Although Stern was listed on her birth certificate, it was not certain that he was the father. At issue in a California court was who fathered the child, who could potentially inherit millions of dollars from Smith's estate. On September 26, 2006, Stern claimed in an interview from the Bahamas with Larry King on CNN that he was the father of Smith's newborn daughter.
After much media attention, on April 10, 2007, Michael Baird, who analyzed the results of a March 21 DNA test, announced the results that confirmed Birkhead to be the father of the baby.[2][3]
