Later that year, theFancy AF Cocktailsauthors bought their first house together.

“Sometimes [decorating a home] can stereotypically be like, okay, the girl kind of does all the decor and the guy just is like ‘I just need these two things,'” Sandovaltold PEOPLEin 2021. “But it definitely wasn’t like that with us. It was a total collaboration, which is great because I like stuff that’s funkier and a little bit louder and Ariana likes things serene and tranquil. So, bringing those two styles together kind of created our own individual look.”

Sandoval supported Madix as she learned tomanage her depression, and she said in October 2021 that her thoughts on marrying the Tom Tom restaurant co-owner had evolved.

“I think the big thing for me is that I’m not really into the whole fanfare of it,” she said onWatch What Happens Live. “It’s really more about the two people. So if it was just about us, you know, I honestly think I would be more open to it. I just don’t want it to be like a big thing about having a giant wedding and a bachelorette party and all that b——-.”
