I read several articles on how they met. It was a set up. Alec frequented a restaurant called Pure Food and Wine and Hilaria was friends with the owner, Sarma Mengallis. The Alec Baldwin Foundation later put up 100k bail when Mengallis was arrested for theft, tax crimes and fraud. Sounds like he was duped from the outset, but surely he'd have realised eventually that she wasn't actually Spanish? Though he alludes to it in interviews and also put out a tweet "dedicated to all Spanish yoga teachers"
Naming her kids all Spanish names though. She was really in for the long con with that one. I feel sorry for them. It will be awful when they are old enough to be aware of all of this.
