But the mystery seems to have solved itself fairly quickly, with Page Six saying a source confirmed that newborn Lucia was born via surrogate. Speculation around Hilaria and Alec choosing to use a surrogate was rife after fans noticed Hilaria following a surrogate account on Instagram.
“We are so in love with our daughter, Lucia,” Hilaria wrote on Instagram, sharing a photo of her newborn. “Just like your brothers and sisters, you are a dream come true.”
To be fair, the couple have never actually confirmed that Lucia was welcomed via surrogate, with Alec responding to a person on Instagram who questioned the close birth dates between the two children with “You should shut the f**k up and mind your own business." A fair statement given it's no one's business but theirs.
Their rep also responded to Page Six, saying “We’re still not issuing a statement or confirming anything – what she posted stands."
The couple now have six children - Carmen, 7, Rafael, 5, Leonardo, 4, Romeo, 2, Eduardo, five months, and newborn Lucia. Alec is also father to 25-year-old daughter Ireland Baldwin with his ex-wife Kim Basinger.
Most recently, Hilaria shared this sweet snap of daughter Carmen with Lucia.
