A 19-year-old girl only is insisting she is pregnant with baby Jesus, despite all six of the pregnancy tests she's taken coming back negative.

Identified only as Haley, she appeared on the Dr Phil show saying she was just days away from giving birth to her baby and that it's not just any baby, it's Jesus.

Despite her own family members and church pastors telling her it's not true, Haley says she is "not stupid" and "not crazy" to believe that she is pregnant with Jesus.

"I don't care if my family disowns me. It really comes down to if you are a true believer in Jesus or not. I know it's Jesus," she said.

She added: "When I give birth to my baby, no one is going to deny him because he's my savior."

Haley says evidence of her pregnancy is her weight gain of at least 22 pounds. She also describes feeling her baby kick inside of her.

"I know my pregnancy is real. I've gained at least 22 pounds," she said. "I was sleeping one night and my baby punched the bottom of my stomach and kicked me, and I can feel his head right here, right below my belly button."

Haley appeared on the show with her mother Kristi and sister Adriana, who are fed up with her claims and think she is really just a "compulsive liar" and "delusional".

Kristi said her daughter had previously claimed her father was the rapper Eminem, that she donated a kidney to her brother, and she was a contestant on American Idol.  

Her claims about being pregnant with baby Jesus, however, have pushed her mom and sister to despair and caused considerable tension in the family.  In an effort to resolve the conflict, Dr Phil had Haley checked out by Dr Travis Stork from The Doctors.  

He conducted an ultrasound which came up blank and he suggested the movement she could feel in her stomach was actually from distended bowels, not a baby.  His verdict: she is not pregnant.

Haley dismissed Dr Stork's conclusions, as she has done the previous six pregnancy tests, but she has, however, agreed to work with a psychologist provided by Dr Phil.
