Speaking with PEOPLE last November, the fitness instructor said that "during times of COVID, it very much feels like we're done" expanding their family.

"Everybody's asking me this question. I don't know. I've said in the past that I was done when I wasn't done. I think, right now, I'm so tired," she explained at the time. "And I feel, just with COVID — it's just insanity," she said at the time.

News of her sixth child's arrival also comes a month after the Mom Brain podcast co-host apologized in February for not being "more clear" about her cultural background when she was accused of misrepresenting her heritage in late December. Social media users alleged she had falsely claimed to have Spanish roots and took on a Spanish accent despite being born and raised in the United States.

"I've spent the last month listening, reflecting, and asking myself how I can learn and grow. My parents raised my brother and me with two cultures, American and Spanish, and I feel a true sense of belonging to both," said Hilaria, who previously confirmed that she was born in Boston and her birth name is Hillary. "The way I've spoken about myself and my deep connection to two cultures could have been better explained — I should have been more clear and I'm sorry."

30 Rock alum Alec supported his wife throughout the scandal, with a source previously telling PEOPLE that the actor was "supportive and has tried to cheer her up."
