Bristol Palin gave birth to daughter Sailor Grace Dec. 23 and, even though the father of the baby still remains unknown, her ex-fiancé Dakota Meyer hinted that he was the dad when he posted a photo of the newborn girl in the hospital shortly after she was born writing, "Best Christmas present ever!!! I couldn't be more proud of this little blessing!" Palin has yet to comment on who the father of her child is, but Meyer is apparently claiming Sailor as his — and he now wants custody.

Meyer filed legal documents claiming he's the biological father, according to TMZ. If he is the father, he wants a judge to award him joint legal and physical custody. He also wants child support.

When Sailor was born, Meyer was apparently not at the hospital during the delivery, but showed up the day after, as HNGN previously reported. At the time, it was unclear what sort of role he would be playing in her life.

The two called off their wedding, for unknown reasons, about a month before Palin announced she was pregnant. All they asked was that everyone respect their privacy.

Sailor is the 25-year-old daughter of Sarah Palin's second child as she already is a mother to 6-year-old son Tripp, who she had with her other ex-fiancé, Levi Johnston.
