Earlier this month, Hilaria got candid on herInstagram Storyabout juggling son Edu and newborn daughter Lucía, writing: “Having two small babies is so fun and cute.there are also challenges. like Lucia just had an explosion and I have Eduardo rolling around…so I’m just gonna lay here, covered in poop, entertaining Edu…until I get a genius idea how to get out of this 💩 situation.”

News of her sixth child’s arrival came a month after theMom Brainpodcast co-hostapologizedin February for not being “more clear” about her cultural background when she was accused ofmisrepresentingher 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.”
