A Florida woman reportedly in a “romantic sexual relationship” with her brother was charged after giving birth to his baby, officials said.

Pauline Elizabeth Martin, 33, told investigators she and her brother were living as a couple in Groveland when she became pregnant with his child, the Orlando Sentinel reported.

Authorities said they began investigating the woman, who is a McDonald’s cashier, after the baby was born Nov. 21 with “severe medical problems.”

The newborn was immediately transferred to get specialized care at Winnie Palmer Hospital for Children in Orlando, where genetic testing revealed the parents were related, the Daily Commercial reported.

Neither parent completed the information on the baby’s birth certificate, according to authorities.

Deputies interviewed the mom at her workplace last week in Leesburg, and she allegedly admitted she has been romantically involved with her brother for the past five years. The siblings reportedly last had sex March 21.

“She said she was going to end her relationship with her brother because she knows it is wrong,” the police report stated, according to the Orlando Sentinel.

Martin was arrested Friday on charges for incest and resisting without violence, according to court records. She was released the following day from Lake County Jail on $3,000 bond.

The mom is next scheduled to appear in court April 16.

Officials said they plan to speak to her brother but have been unable to track him down, the Daily Commercial reported.
