Pregnant Gypsy-Rose Blanchard Took a Pre-Birth Paternity Test to Prove Ken Urker Is Her Baby's Father: 'Very Unusual' (Exclusive)

Gypsy-Rose Blanchard has completed a paternity test ahead of the birth of her first baby, PEOPLE can confirm.

The 33-year-old and her boyfriend Ken Urker are currently expecting their first baby together, but as a Louisiana attorney previously confirmed to PEOPLE, her ex Ryan Anderson will be listed as the father on the infant's birth certificate if they have not been divorced for 300 days at the time of the birth. Currently, Blanchard and Anderson are still married, per Lafourche Parish court records.

Following the realization of this Louisiana law, a source close to Blanchard tells PEOPLE that she completed a procedure called a Noninvasive Prenatal Paternity test (NIPP) to prove that Urker is the father of Blanchard's daughter on the way.

Anderson's attorney, Randy J. Fuerst, has told PEOPLE that Blanchard's test before birth was "highly unusual."

"In the 40-something years of practice — of myself and other attorneys in this office for combined longer periods of time — we have never seen someone do a pre-birth paternity test because there is no need to do that," Fuerst tells PEOPLE. "Usually you wait until the birth of the child and then the paternity test is done. And if it turns out, as we suspect, the child is her current boyfriend's, then the birth certificate is changed with an order of the court subsequent to the birth of the child."

"It's highly unusual and unnecessary, and it's a procedure that [sometimes] requires taking DNA from an unborn child," Fuerst adds. "So that's her business and she's certainly welcome to do it. Ryan has no objection to it, but, just as his lawyers do, finds it very unusual."

The source close to Blanchard also tells PEOPLE that the test she completed was "the non-invasive kind."

"It’s very low risk," adds the source. "It only required her blood and a swab from Ken’s DNA from his cheek, since [the baby's] blood is circulating in her [Blanchard's] body.”

According to the Cleveland Clinic, "A NIPP test analyzes fetal DNA in the pregnant person’s blood. A provider will take a blood sample after your eighth week of pregnancy. They send the samples to a lab, where a specialist analyzes trace amounts of the fetus’s DNA in the blood sample and compares it to the DNA in a cheek swab from the potential non-birthing parent. An NIPP is 99.9% accurate and very safe."

Blanchard and Urker announced that they are expecting their first baby together in January 2025, sharing the news in July. The Gypsy Rose: Life After Lockup star filed for a divorce from Anderson, whom she married in 2022, in April 2024.

Beau Brock, an attorney in Louisiana who has practiced family law, among other things, for 32 years, spoke with PEOPLE in July about why this Louisiana Law is in place, and how it will affect Blanchard, Urker and Anderson.

"There's a legal presumption in Louisiana that if you have a child while you're married, it's presumed to be the husband's child. It's done that way to protect the child," Brock told PEOPLE. "All the laws in Louisiana concerning paternity are designed to protect the child and make sure the child has a father and a mother to provide for them. So that presumption can be overcome by DNA and that's what people have to do."

Aside from taking a DNA test to determine the father, Anderson could have signed an affidavit confirming that Urker is the father, ensuring Urker's name will go on the birth certificate. However, as Brock told PEOPLE, "In these kinds of situations, we always recommend to do a DNA test because there are overlapping hookups that are possible. You don't know."
