'Biological Father:' Crazy Baby Mama 'Needs Help'

Julian Bleecker, the guy Claire Elisabeth Fields Cruise claims is the biological father of one of Michael Jackson's kids, tells us it's all a "ridiculous accusation." Knock us over with a feather.

We just got him on the phone.... He says "Cruise" has been calling him lately to organize a high school reunion. He eventually had to cut off contact because she sounded "not quite right."

The last time he spoke to her was just under a week ago, when she asked him to be her "unofficial fiancé."

Crazy Baby Mama Fact #546: According to the lady herself, she changed her last name to "Cruise" when she married Tom in the 9th grade.
