Matteo Artemovich and Buddy Dessert may be family, but they're also the best of friends.

Total Bellas stars Brie Bella and Nikki Bella, both 38, recently spoke to Entertainment Tonight about the sweet bond their sons have with each other. Brie is mom to Buddy, whom she shares with husband Daniel Bryan, while Nikki shares son Matteo with fiancé Artem Chigvintsev.

"They are just wild. Our boys are wild," Nikki told the outlet of their sons.

"Yeah, we have been used to these wild boys," Brie added. "It's funny because they are already a perfect little tag team. I feel like it's baby mania every day at the house.

Nikki welcomed Matteo with Chigvintsev on July 31, less than 24 hours before Brie welcomed Buddy on Aug. 1. Brie and Bryan are also parents to 4-year-old daughter Birdie.

At the time, ​​the Bellas opened up to PEOPLE about their sons, sharing that they were placed into hospital rooms right next to each other, and they got to meet their new nephews for the first time.

"What's crazy about Buddy and Matteo is they both have the same scream-cry," Nikki said. "It's the cutest high-pitch noise and they're identical. Even their coos are identical and they're so cute."

Though the sister duo is enjoying motherhood, Nikki admitted to ET that she's not looking to expand her family anytime soon.

"For me, no," she said of baby No. 2. "I think Artem hopes for something different and wishes for that. You never know what the future can hold, but I don't see that happening anytime soon. God, I hope not. I am so tired."
