'Hitler's' Nazi dad just can't get to see his son!

A white supremacist who named his oldest son Adolf Hitler has been denied form visiting his 2-year-old son.

Heath Campbell strolled into a New Jersey courthouse on Monday dressed in full Nazi regalia - to try to convince a judge to allow him visitation with his toddler, Heinrich, the New York Post reported.

Campbell and his now-estranged wife, Deborah, had their four children taken away from them in 2010 amid charges of violence in their Holland Township home.

The Nazi-loving pair appeared on authorities' radar after they publicly complained that a local ShopRite supermarket refused to write 7-year-old son Adolf Hitler's name on a cake in 2008.

In addition to the sons, they have two daughters - JoyceLynn Aryan Nation Campbell, 6, and 5-year-old Honzlynn Jeannie Campbell.

All of the children were placed in foster care in one home. The two girls and Heinrich - named after Hitler's right-hand man, Heinrich Himmler - remain there, while Adolf was moved to another after allegedly causing trouble.

The three oldest kids have since been adopted, and Campbell has been rebuffed by the courts in his efforts to see them.
