Larry Birkhead has vowed to keep fighting the paternity suit until he is officially named the father of Anna Nicole Smith’s new baby, Dannielynn.

In an open message to two month old Dannielynn posted on his website, Larry says: “I constantly wonder what kind of person would steal a child from another.”

“I thought at first maybe because your brother [Daniel Smith] was taken from your mom was the reason, but then I realized she started planning on keeping you from me all the way back in May.”

“I am ready to fight anyone and everyone that gets in my way. One day, you will thank me for fighting for you when others expected me to just walk away.”

Anna Nicole is still hospitalised in the Bahamas while she recovers from pneumonia and exhaustion. Her partner Howard Stern is named as the father on Dannielynn’s birth certificate.
