“We are beyond thrilled to announce the birth of our daughter Lyla Maria Schwarzenegger Pratt,” the caption onboth parents' posts readat the time. “We couldn’t be happier and we feel extremely blessed! Love, Katherine and Chris.”

The infant’s middle name is a nod to Schwarzenegger’s ex-wife and Schwarzenegger Pratt’s mother,Maria Shriver, who then commented on her daughter’s post, “So happy for you Lyla Maria is so blessed to have you both as parents you are going to be a amazing mama you already are !!!”

During Schwarzenegger’s late-night guest appearance, Kimmel also pointed out “how great” it is that Lyla gets to visit the actor’s animal-filled home, where theTerminatorstar allows his miniature horse Whiskey and donkey Lulu to roam freely.

“She has already been over here several times at the house and she sat on top of Lulu and on top of Whiskey,” Schwarzenegger said of Lyla. “And I think she’s going to be a great horseback rider.”

“I said, ‘Katherine, come on, now. I’ve held enough children in my hands. I know exactly what I’m doing. I’m an expert in that stuff,’ " Schwarzenegger added. “She just freaks out and does it. [But] I think it’s natural.”
