Ireland, the oldest of Alec's daughters with Kim Basinger — who was married to the actor from 1993 to 2002 — announced baby Holland's arrival on Thursday.

The new mom shared a photo from the hospital, where she could be seen holding her infant daughter in one arm, with the baby's father, her partner RAC, leaning into them both.

"Holland 🩷," she captioned the shot. In the comments section, Hilaria added some heart emojis.

Hilaria also posted a photo of her own brood earlier on Thursday, where she expressed her family's excitement about the new arrival.

"All of these aunties and uncles and us grandparents are so excited that Holland is here," the caption read. "We love you so very much!"

And Alec, 65, shared his excitement on Instagram Friday morning.

"My first baby had her first baby," Alec said, captioning a candid throwback photo snapped as a young Ireland sat on his lap. "Much love to the three of you!"

Back in January, Hilaria shared a video on Instagram of Alec sitting with his younger kids as daughter Carmen explained to the rest of her siblings — Ilaria Catalina Irena, María Lucía Victoria, Eduardo 'Edu' Pao, Romeo, Leonardo Ángel Charles and Rafael Thomas — that big sister Ireland was going to be a mom.

"So you guys know what uncle means. It means that your sister or brother is pregnant, or they have a kid," Carmen said, pointing to each of her siblings and telling them they'll be an uncle or an aunt with the new arrival.

"What am I?" Alec asked, to which Carmen replied, "You're going to be a grandpa."
