Courtney says Amie claimed she was pregnant with a baby girl after one date with her boyfriend. “Nineteen weeks into her pregnancy she claimed to have had a miscarriage,” Courtney says. “Amie’s boyfriend and I never saw a single shred of physical evidence that the baby did pass away.”

Courtney says four weeks after Amie claimed she lost her baby, she said she was pregnant again, this time with twins.

“Over the process of her pregnancy, she showed us multiple ultrasounds and once again, there was never any personal information to indicate that they were Amie’s. And, her boyfriend was never able to attend a single appointment because Amie would come up with a convenient excuse,” Courtney says. “I really became suspicious of Amie when she wasn’t getting any bigger … I thought it was absolutely crazy.”

Amie insists she was pregnant all three times and says she is disgusted by Courtney’s false and hurtful accusations.
