13 years after tying the knot, Alec Baldwin's wife Hilaria admits she didn't, 'quite understand' what a prenuptial agreement was on the premiere of The Baldwins.

TLC debuted the new reality series on Sunday, which follows the 66-year-old actor, his 41-year-old wife and the seven young children they share.

The actor and former yoga instructor started dating in August 2011 and tied the knot in June 2012, sharing seven children together - Carmen, 11, Rafael, 9, Leonardo, 8, Romeo, 6, Eduardo, 4, Maria, 3, and Ilaria, 2, along with Alec's 29-year-old daughter Ireland, from his marriage to Kim Basinger.

Halfway through the premiere, the couple opened up in a dual confession about Hilaria signing a prenuptial agreement.

While Alec admitted it was, 'awkward,' he said, 'After my first marriage (to actress Kim Basinger), I said, "Let's have a prenup,"' admitting, 'She wasn't happy about it.'

'First of all, I just don't understand quite what... it is awkward, but I don't actually quite understand what a prenup is.'

She added, 'You're like, "After a certain number of kids, it's this." I was like, "You know what? I'll just sign it," which was very stupid of me back then. Now I will read it again,' she said.

Her husband also said they used to be far more 'collaborative,' though at some point that changed as well.

'I'd say we'd argue, we'd discuss, we'd have some accommodation about what we were gonna do, how we're gonna live,' Alec began.

'And then, one day, you kind of changed. And no matter what I said, you were like, "No! Here's what we're gonna do,"' he added.

Hilaria responded, 'So, yes, I agree that that's your reality of it. But what I used to do is I would say yes and then I would do whatever I wanted, and I would just keep it from you.'

He joked, 'You'd gaslight me?' but she insisted, 'No, no.'

They also discussed her using both English and Spanish, with Alec insisting in the confession, 'Let's talk slower. Let's talk slower. You're speaking English in a Spanish cadence, which is always perilous for me. Slow down. Just a kiss. I can't understand you.'

Hilaria added in confession, 'I'm raising my kids to be bilingual. I was raised bilingual. My family, all my nuclear family now lives over in Spain.'

'I want to teach my kids pride in speaking more than one language. I think just growing up and speaking two languages, is extremely special,' Hilaria added.

She continued, 'Love English. I also love Spanish. And when I mix the two, it doesn't make me inauthentic. When I mix the two, that makes me normal.'

Hilaria admitted of the controversy over her heritage, 'I'd be lying if I said it didn't make me sad and it didn't hurt, and it didn't put me in dark places.'

'But it was my family, my friends, my community, who speak multiple languages, who have belonging in multiple places and realize that we are a mix,' she said.

'Of all these different things, and that's going to have an impact on how we sound and an impact on how we articulate things and the words that we choose and our mannerisms. That's normal. That's called being human,' she said.
