Brie and Nikki Bella's sons are "spiritual twins"

Brie - who is engaged to Artem Chigvintsev - said: "Obviously, I do call them spiritual twins, but it's like they're legit siblings. It's like they're used to each other."

Nikki added on the Bellas podcast that the cousins are "half siblings."

And Nikki also revealed that her son Matteo recently did a "half roll" to get closer to his cousin Buddy.

She gushed: "He's like a koala bear, how he holds onto me. So, I felt like it made him do a half roll so he could koala Buddy."

Meanwhile, the siblings recently revealed that they are set to move with their families to Napa Valley in California from their homes in Phoenix, Arizona.

Brie said: "Yes, I moved to Napa Valley! I feel like everyone's like, 'Duh, of course they did.' My sister and I have always loved Napa Valley. We have a wine here. We're always here."

Whilst Nikki added: "And guess what? I'm doing it with you. There's the big surprise. I'm also moving to Napa Valley - well not just me, but my family, Artem [Chigvintsev], Matteo and I."

Brie - who also has daughter Birdie with husband Daniel Bryan - confirmed the news after reports swirled when fans spotted their houses were up for sale.

She shared: "It was a very last-minute move that happened very spontaneously, but the cameras of 'Total Bellas' of course caught everything. And I feel like I should just let the magic happen on TV; let you guys find out on television why we decided to move, because it is a little bonkers ... We majorly downsized. We wanted to be more simple. You guys have always known how Bryan and I are, so we just were like, we need to get back to who we were before kids and let's simplify our life and live more country. And we're doing it."

Nikki said: "We downsized as well because the Danielsons rubbed off on us in COVID. And just seeing a summer in Arizona, I mean, I already believed in global warming, well then I really believed in global warming. I mean, my water broke because it was 118 degrees ...

"I've always loved the finer things in life and I will say, the one thing COVID taught me was to simplify my life in all areas. I just started to look at all my things and I was like, what does this really mean? What does this mean when we're in this situation? What do I really want my money to go towards? For me it was like, seeing beautiful parts of the world, having amazing experiences and new memories with my family."
