Nicki Minaj admits her marriage to Kenneth Petty “got testy” following the birth of their son.

The “Barbie World” rapper — who welcomed her baby boy in September 2020 during the COVID-19 pandemic — said in a new interview that she and her husband navigated their son’s infant stage without any help other than a few visits from a grandparent.

“I’m not going to lie, things got testy between us,” she told Vogue in her December 2023 cover, published Thursday. “Because of our history, I think we knew we’d get past it. But there’s no such thing as confidence in parenthood.”

She added, “I kind of wish that someone had told me — although I’m sure I wouldn’t have been able to understand it — that there’s a level of anxiety, and you think it’s going to go away, but in fact it gets scarier.

“So often you think: I don’t know how to do this!”

Minaj, whose real name is Onika Tanya Maraj, and Petty met in the ’90s while attending the same high school in New York City.

They lost touch for years before reconnecting in late 2018.

The couple tied the knot in October 2019.

The “Super Bass” rapper, 40, announced on Instagram in July 2020 that she and Petty, 45, were expecting their first child.

“#Preggers💛,” she captioned a photo of herself cradling her baby bump in a bejeweled bikini and lucite high heels.

The pair have not revealed their now-3-year-old son’s name, only publicly referring to him as “Papa Bear.”
